  • Is Pure TDS 0 Water Actually Bad for Making Clear Ice?

    Here's an interesting problem and solution: James Hogarth reached out to me to describe the following. He is using water filtered with a Zero Water filter in a clear ice system. This filter removes all the major dissolved solids in the water, and it comes with a little TDS meter to verify it. But the supposed-to-be-clear ice that comes out from this water has streaks remaining, but regular tap water doesn't. 

    My tap water has a terrible taste, however, when I freeze tap water [in the Wintersmith’s Phantom] it does freeze perfectly clear. The bad news is that if I then thaw the water it still retains a bad taste. It is improved but still not good.

    Curiously, the ZeroWater filter comes with a Total Dissolved Solids meter, and while not the most sophisticated meter in the world, it reads around 110-120 on tap water and perfect 0 for the thawed water. 

    So right now I either get great tasting ice with air bubble streaks, or perfectly clear ice that tastes terrible.

    Even distilled water gave me streaks of air bubbles. My freezer was always right around 0 degrees, and multiple different molds, no mater what, boiled or not, still got streaks.

     

    He theorized that his water was actually freezing too fast without salt and other minerals in it that would naturally slow the rate of freezing. 

    So to test the theory, he tried adding table salt to TDS 0 water – and it was successful! He added a concentrated salt solution to the rest of the water to try to bring it around 135 ppm before freezing. 

    I know that ice crystals will push out salt molecules as the ice crystalline structure does not have room for it. Freezing water is one method for desalination of sea water for this reason, it just isn’t very energy efficient.

    The melted ice tastes just as good as the filtered water. From the top half [the clear part], the meter reads 6 and the bottom half 163.

    So after a few more batches of ice, and a few bottles of whiskey, it seems that around 140-180 ppm of table salt in the ZeroWater is ideal. I get crystal clear ice, and when I melt the ice and test it, it’s usually 6ppm salt or less.

     

    We knew that freezing water pushes the trapped air and impurities (including the minerals) to the last part of ice to freeze. What's interesting here is that at least in this case, the presence of "impurities" while freezing seems to improve the clarity of the ice, and we can theorize that is because they slow the rate of freezing. 

     

    Hogarth later tried other minerals, including mineral drops that are sold to supposedly make water healthier. He found they acted in much the same way, concentrating in the cloudy part of the ice. 

    Trace Mineral Drops: starting at 204 ppm, melts to 23 ppm. So something is clearly less filtered from directional freezing than salt or calcium chloride. Both of which could be as high as 240-250 ppm and the melted ice would be around 6ppm. I don’t have the tools to tell you what it is though.

     

    So I'll leave this at that. To replicate it, I (or better yet, you) could try freezing two identical quantities of water in identically-shaped insulated trays: one with TDS 0 and one with some dissolved solids.

    This might not be an issue if your freezer temperature is higher and closer to the freezing point, but most freezers have maximum temperatures much lower than that for food safety.

  • Smoothing Thermos Ice Spheres Using an Ice Sphere Press

    I have several ways to make ice spheres at home, but the one that takes up the least amount of space is using a thermos and ice ball mold

    This method produces nice large ice spheres but they're not as smooth and perfect as those made in the IceOlogy trays or big cubes pressed into spheres using an ice ball press

    So I thought I would try using the ice ball press to smooth off the surfaces of ice balls made in the thermos method. It works only just okay – because the ice ball press makes larger spheres than the ice ball molds I have. They come out a little odd shaped as the fit is not perfect. A better size match would be better.

  • Designs on Clear Ice Cubes Using Clay Stamps

    Patterned ice with clay pot stamps17Lately I've been making designs on ice cubes using the Ice Designer tool or these Cookie Stamps. I even wrote a story about how Patterned Ice Conquered Drinkstagram

    Well in my fairly regular perusal of Amazon for new ice stuff I came across these stamps that are used to impress patterns into clay and other materials. I thought they just might make cool patterns in ice cubes, and surprise, surprise – I was right!

    The first step is to make clear ice in one of the many ways demonstrated in my ice experiments.

    I first tried them at room temperature and the pattern didn't go deep enough. Then I heated them up a bit – atop my toaster actually. Then pressed the ice on them. It worked great!

  • Dividers For An Ice Block

    As you know, I make ice in an insulated cooler in the process known as directional freezing first demonstrated here on Alcademics in 2009.

    Lately I've been playing with an ice sphere press to make super nice looking ice balls.

    Oth_icebalmakerx_0070_blk_web1_1
    Oth_icebalmakerx_0070_blk_web1_1

    But the problem is that the ice spheres are about 2.7 inches in diameter and there is no 3-inch ice cube tray that I know of. In order to make roughly 3-inch cubes, I make a whole cooler full of clear ice and then cut it up to the size that will fit in the ice ball press. Cutting up a slab of clear ice into these shapes isn't that much of a hassle, but still I am lazy and want to find a better way. 

    So I decided to hang dividers in my cooler that would make the ice easily break into sections. This is a work in progress. I first tried one thick plexiglass divider that didn't fit across flat. It was really hard to get the ice out of the cooler afterward, and I figured out that it works best when you can see all the edges of the plastic. But anyway it worked.

    Next I experimented with a thick plastic sheet I purchased from Tap Plastics, and then cut to size. It works best when the plastic is straight across the cooler, rather than curved.

    Then I realized the defrosting plate that I use to smooth the edges of ice actually fits flat across the width of the cooler. It actually slides right into the grooves in the cooler. Unfortunately, this defrost plate is no longer offered online, so I've been experimenting with others. I'll let you know if I find another one that fits perfectly.

    In any case, the metal plate slides out of the ice easier than plastic does. I also learned that it's far easier to separate the block from the dividers if I don't let the block freeze for more than two days, which gives me about 3 inches of ice in the cooler.

    Not that I have three sections of ice instead of one block, I can cut each slab in half to get roughly 3-inch cubes just like I wanted. It's a start! 

    Anyway, I'll keep you posted on the progress of this project. 

     

  • Make Clear Stars and Hearts Ice with Silicone Cupcake Liners

    You can make clear ice cubes in a tray in a cooler by punching holes in the bottom of each cube compartment and setting the tray on a riser. This is described here. Most commercial clear ice cube trays work similarly. 

    But cubes are not the only shape of clear ice you can make in this method. Using these cheap silicone cupcake liners from Amazon:

    61-Ucg06exL._AC_SL1500_

    I poke holes in them (using this hole punch) and set them on a riser in a cooler. I then filled the cooler with water up to the level of the top of the cupcake liners. I let them freeze for 24 hours, though I could have pulled them out sooner.

    The silicone cupcake liners pulled out of the ice surprisingly easily, and the ice slipped right out.

    They were hard to photograph with liquid in the glass, because they're so clear the ice disappeared. For the ones with liquid in them, I only have a little bit of liquid in the glass. 

    I'd love to think of a way to best display them in cocktails. Perhaps tucked into crushed ice at the surface of a drink. Of course they'd also look great with colored ice, but then we wouldn't have had to poke holes in the cupcake liners in the first place!

     

  • Making Patterned Ice Cubes with Cookie Stamps

    As you're probably aware, patterned ice is the new logo ice

    You can make patterned ice with an ice designer ($160) or a meat tenderizer ($13), and recently I purchased some cookie stamps ($27) to give those a try. 

    The round shape can be limiting, but they're pretty large and will cover a 2" cube. A new addition to my icy arsenal.

  • An Easy “Trick” for Removing Clear Ice Cubes from Trays

    A lot of times I make clear ice in a Ghost Ice or Clearly Frozen tray and after a day and a half or so, it's plenty of frozen enough. If I let it go for two days or longer it is harder to remove the ice cubes – or rather, harder to separate the tray on top from the reservoir/cooler on the bottom.

    Clearly frozen tray13

     

    Often I will realize as I'm heading out the door to work that I should empty the trays so that they don't freeze much longer, but don't want to take the time to pull them or wait for them to warm up a little. 

    My "trick" for this is to simply move the trays into the refrigerator and leave them there all day.

    Ice stays frozen surprisingly long in the refrigerator. Blocks of ice are still solid, and in the case of cubes, putting them in the fridge all day actually helps the trays pop off the cooler, and helps them slide right out of the trays. 

     

    Clearly frozen tray4

  • The Cool New Ice Trend In London, 1873

    Screen Shot 2022-09-05 at 11.13.36 AMI was searching for some information on Wenham Lake Ice and stumbled across this article in The Food Journal, published in London in 1873. 

    Wenham is a lake in Massachusetts and its ice was famous and exported to London (I have some interesting info about that in Doctors and Distillers), but by the time this article was written, the Norwegians had renamed one of their lakes Wenham Lake in order to sell it by that name. Pretty sneaky!

    Information about that is in the story below, but mostly I'm intrigued by how ice is described as this new material and the writer describes possible uses for it. 

    I highlighted the fun stuff in bold. 

     

    The use of ice has gradually increased among our population in the last twenty years, at an ever-accelerating rate, although it is as yet by no means as necessary an article in our domestic economy as among our American cousins. Boston is said to consume double the quantity of ice that contents London; yet, wherever we go, "Iced" heads the advertisement of drinks in our places of refreshment, and refrigerators and various contrivances for the application of ice are advertised extensively. In such an unprecedentedly hot season as the present, the British public slowly but surely wakes up to the necessity of utilising the wintry cold products to balance the summer heat. Ice not long ago was accounted a luxury; it is not yet, but we hope soon will be, esteemed in the household, as well as in places of public entertainment, a necessity; economy advises it, health and taste demand it, but so long as we depended on the uncertain home supply, expense forbade it. The hardest English winter, moreover, though it might fill private ice-houses and the ice-wells of our dealers, would not yield ice of a reliable purity, or of a durable degree of congelation. The importation of Wenham Lake Ice from America was the first step in the process of bringing within reach of every one ice of a strength, if we may use the term, which would bear transit and keeping, and a purity which would allow a lump to be dropped in to cool, as sugar to sweeten, any beverage. Various attempts have been made to manufacture ice on a large scale; the use of steam-power has enabled enormous quantities to be produced by one process ; but the London market — and, by the northern ports, the various English markets—are now altogether supplied with ice from Norway. The amount is influenced by the severity or mildness of our winter, and varies from 30,000 to 50,000 tons; the ice from the rivers and ponds in the environs of London is by no means neglected, for it is gathered and stored, and, as rough ice, is preferred for all exterior purposes. The various trades— fishmongers, brewers, confectioners, butchers, and poulterers— prefer the English ice, if procurable, not only as cheaper, but because it yields more readily to the liquefying powers of the salt mixed with it (usually 3 lbs. of salt to 10 lbs. of ice), and thus cools or freezes more rapidly than the hard, smooth blocks of foreign ice; it has, as a leading ice merchant remarked, " more gravy in it.*' Thus the patriotic mind need not fear that the Norwegian ice, like the carpentry and firewood, will supersede our home production. It must be borne in mind that ice which is mixed with our food or drink must be pure, and all ice that looks clear is not necessarily pure; for our analysts tell us that, as clear sparkling water may hold in solution poisonous matter, so crystalline ice may, when dissolved, actually prove putrescent, and by smell betray the foulness of the water whence it came; or else it may contain unsuspected unwholesome mineral salts. The mountain tarns and lakes of Norway, fed by the melted snows, and uncontaminated by drainage, yield a pure wholesome ice, and the Norwegian bonders have found a new source of industry and profit in the ice harvest. The Oppegaard Lake, now re-christened the ** Wenham Lake," and the property of the company of that name, is but one of many which rival, though do not surpass it, in the undoubted purity of its waters. The process of ice-ploughing and storing need not be described. The ports of Drobak, Drammen and Christiania, Lauwig and Kragero, Wiburg and Brockstadt, are the chief emporia, where the huge crystalline blocks, weighing from 2 to 4 cwt., are stored, waiting for the opening of the navigation and the demands of heated London. By sailing ship and steamer, sometimes in advance of the demand, sometimes in answer to a hurried telegram, the supplies of solid coolness and refreshment come. The king of the ice trade is Mr. Stevenson, whose trade thirty years ago was but 300 tons annually, and now reaches 600 tons per week; next come Messrs. Leftwich, and Carlo Gatti, who deserve the praise of having brought ice within reach of even the humblest. We have visited the ice stores of Messrs. Stevenson ; the wells consist of enclosed brick chambers of 50 cubic feet, with double doors, in thick double brick walls, excluding all light-; each chamber contains 1,000 tons. A steam lift hoists the cartloads of ice to the top, and it is then shot down just as coals are loaded into a collier. The cold, dark atmosphere, with the sfeam rising from the icy floor, might suggest a dream of one of Dante's circles. Near the principal wells in Cambridge Street, Hackney Road, are others of an older construction, built underground, and of less capacity. Above the roof of the wells is a loft with open sides, for storing and drying sawdust, of which 200/. to 300/. worth is used annually in the packing of the ice sent out. The huge blocks come over in the vessel's hold without any packing, and are handled like blocks of marble. But many a one who has vexed his soul with trying to break a lump of ice will be surprised to learn that to split them into manageable pieces it is only required to take a sharp-pointed "ice-dibber" like a large brad-awl, and with this to stab the surface, making several slight holes in a line, when the block splits without any further trouble; to divide a small piece of the hardest ice, you need only take a bodkin and sharply prick it, and it will break up without flying into your face or your neighbour's lap—wit herein surpassing strength.

     

    The ice as imported can be sold at prices var}'ing from 30J. to 40X. per ton; but, of course, the waste and fluctuations in demand, and the difference in the rate of supply to large and small consumers do not allow it to reach the general public at that rate; but the supply is always equal to the demand; and the hardy Norseman, by the beneficent intervention of Messrs. Stevenson, Leftwich, Gatti, Kent, the Wenhan\ Lake Company, or Messrs. Duus and Brown, of Fenchurch Street, can furnish us all with this cheap luxury, whenever that happy time comes in which Londoners are as wise as the Americans in the use of ice. We have already enumerated the trades in which ice is used: the fishmongers and daitymen long monopolised it as a preservative; now the butchers and poulterers employ it extensively; the brewers use rough ice to cool their wort, or even throw the Norwegian blocks into the vats; bacon, too, is cured by its help. The public more directly appreciates the luxury of ices and iced drinks, and, in the household, the benefit of refrigerators ensuring cool water, solid instead of oleaginous butter, and joints kept long enough to be tender, without disappointing the mistress and destroying the equanimity of the master. We will not attempt to enlarge upon the different varieties of ice pudding, dessert ices, etc. Next to their richness and flavour, the great secret of their preparation lies in the care with which they are whipped or churned during congelation. Most machines for this purpose are constructed on the rotary principle. Kent's Paragon Freezer appears adapted to save labour, and the Imperial of the Wenham Company is also a good one for the purpose. Ash's Piston Freezer, as its name imports, is worked up and down, and an advantage is obtained of being able to ice wine, make, block ice, and freeze dessert ices in one operation: in all these either ice and salt is used, or else freezing powders. A very simple one can be made Sy mixing i lb. nitrate of ammonia, i lb. carbonate of soda, and pint of water; or a more intense freezing mixture, with 2 lbs. pounded ice and 3 lbs. crystallised chloride of calcium or salt of lime. It may not be amiss to remark that a quantity of ice after meals is injurious, by stopping the secretion of gastric juice, and interfering with the process of digestion. A gastronomic process may also be made against the somewhat senseless fashion of following up iced pudding with post-prandial dessert ices—^that is to say, if you relish your wine. The palate is demoralised. Far better to keep the ices for the drawing-room, for both the digestion of the dinner and the enjoyment of the wine will be improved by the postponement. We will not venture on praise or dispraise of the various ices of the numerous confectioners; we only wonder at the badness of some, and rejoice to see the custom of mixed, or *' Neapolitan," ices becoming general, the water ice, by the harmonious discord of quality and flavour, improving the cream. It is a cause of wonder why, in some confectioners' shops and in theatres, is, should be charged for ices neither so 'good nor so plentiful as Carlo Gatti, for instance, serves in that beautifully decorated caf6 near the Hungerford Pier.

     

    The mention of Mr. Gatti reminds us that the enjoyment of ices is now by no means a luxury confined to the possessor of 6d., for he was the first introducer of penny ices. He himself assured us that in 1851 he sold no less than 3,000,000; and now, though they are not as popular, partly owing to the carelessness of the vendors, there are two hundred shops in London where penny ices are procurable; but besides these we have seen little gamins, such as thrust iht Echo, Sun, and ** box o' lights" in the faces of passengers, standing round a street ice-stall, each with his glass of bi-coloured ice, licking it up, spoons being despised, with great enjoyment, and paying id. only for it. An itinerant vendor, whose stall was in Seven Dials, informed us that on a fairly hot day his average earnings were 71.; his ices, of one colour, were composed of eggs, milk, arrowroot and sugar, and he could sell 5J. worth for 12j. The ice necessary for freezing he bought for 2j. id, per cwt.—English ice. Whit-Monday, with its blazing heat, was a great day for him, for he sold halfpenny ices at Hampstead Heath to the amount of 3/. 15 j. ! At all events they were innocuous, which is more than we can say of all cheap popular refreshments.

     

    We hope it will not be deemed an impertinence to suggest to the reader that wine is very often spoiled by being iced instead of merely cooled. If the wine be bad, especially " sparkling," ice it well by all means, and drink it while effervescing, and you will not notice its quality so much, till afterwards. If good, let it be first cooled, not in ice, but water with some ice in it, so as to avoid excess of cold; for the colder the wine the less its flavour, and you can, if-you choose, sacrifice the flavour to the luxuty of a cool drink. Champagne frappi is a specialiii. The water is frozen, and the delighted but extravagant palate is rejoiced with the spirit and the liqueur. It is to bB remembered that it is needful to wrap a wet cloth round the bottle when removed from the cooler. As for iced cups and mixtures, their name is legion, as may be said of the many refrigerators of all sorts and sizes. Norway, not content with supplying ice, has recently sent over very cheap refrigerators, which certainly seem adapted for simple use, and are decidedly so for households of small incomes. The danger, so often incurred, of the various meats, fruits, etc., being contaminated by any ill-odour, or even by the closeness of the vessel, is admirably obviated by Kent's ventilating refrigerator. The same ingenious inventor has supplied our licensed victuallers with a bottle refrigerator, or ice wine bin, and has met the requirements of small families by a miniature contrivance which can stand on the sideboard, or even ensure a comforting coolness of drink for the sick patient. A very complete and elaborate affair is the '* Duplex '* of the Wenham Company, which can be used either for rough or block ice, and is furnished with a tank for iced water. We would not advise the possessors to use this water for their matutinal tub, however grateful the chill of the water may be. No one over twenty-five, or under, if wise, will subject himself to the injurious and depressing influence upon the system exercised by a really cold sponge bath. We can only briefly touch on the use of ice as a hygienic agent. Not only are iced drinks grateful to the fevered palate, but the sick craving for them may be safely gratified; and we must here mention a fact creditable to the charitable donor, that any sick person, at any hour of "day or night, is supplied with ice gratis at Mr. Gatti’s ice stores, on production of a medical certificate. Ice is the best remedy in coup de soleil, or any headache brought on by exposure to the sun, as its application produces constriction or contraction of the minute blood-vessels, which are relaxed by the heat. For hemorrhage and irritability of the stomach, ice is largely used as a remedial agent. We do not know whether its application is a remedy for sea sickness, but we are sure that the increased employment of it in our hospitals would be of great advantage, and we heartily commend the example of Mr. Gatti's benevolence in ice to our other ice importers.
