Dexas Ice•ology Clear Ice Maker Tray for Crystal Clear Ice, 2 Round Spheres BPA Free Silicone Clear Ice Cube Maker, Craft Ice Cube Molds for Cocktails, Drinks & Whiskey, Gift Ideas

Product works perfectly as intended, and I really enjoy it. I got a small 1.1 cubic ft Whynter freezer as well and this mold fits perfectly in the top compartment with a bin on the bottom for finished cubes. I like how large they are.I had a problem with WHITE FLAKES collecting on the outside of the ice and after experimenting and talking with Dexas support (very helpful and informative), I have some tips. This strange white debris is calcium carbonate or calcium sulfate in the water that precipitates on the outside of the cubes after freezing. The calcium comes from the tap water. I didn't think I had particularly hard water, so this surprised me. It was also odd that it seemed to collect only on the outside of the ice.If this is a problem for you, make sure to thoroughly clean your ice molds. Try soaking them in a bit of vinegar mixture to really make sure the calcium is removed from the molds, and then try again with distilled water.There is a second problem with distilled water though. Distilled water is pure H2O, so there is no dissolved calcium carbonate, no dissolved ANYTHING. The way ice forms, however, requires some sort of initial impurity in the water to start the crystalization. If you make ice with distilled water, you'll end up with these small streaks in the ice that all direct down toward the hold in the center. It's very interesting, and you can try it for yourself.My solution to these streaks is just to put the tiniest bit of impurities back into the distilled water before freezing again. I put just a pinch of salt in each cube. The ice from this is perfectly clear and clean.

Clear ice! I have played with it. I have tried distilled water and boiled. Tap water works very good and is the easiest. I am using our camper's freezer to make the ice. (No room in the house) The water runs through a charcoal filter coming in. First pic is filling up and freezing. Second pic is letting the form sit for a couple of hours and then freezing. Third pic is the form sitting. (I think, to get the air bubbles out.....) I have had good luck with letting it sit. I have found I have to use a bottle brush on the tray about every three freezes. I get a build up on the bottom, of impurities. Easy to use with good results.

This mold and the directional freezing method is just part of the magic! YOU MUST HAVE FREEZER TEMP 25-30 F!! If you cannot control freezer temp then all appropriate steps taken, all the hours you've waited on clear ice will NOT HAPPEN. Not many freezers if any will allow these REQUIRED temps. You can move/adjust the temp controller to Cold vs Colder but even then freezer temp is too low resulting in somewhat clearer ice but ice in the mold will have air bubble streaks pointing in the direction of the hole inside the rubber molding. I have temp probes & a INKBIRD controller for other projects so I will attempt to turn freezer on/off to hit the required temp ranges.

I could not be happier with this product! The last time I tried my hand at clear ice cubes was years ago before any of these specialized trays existed, and you had to punch holes in a silicon ice cube tray and then put it in a cooler in your freezer. This product made it so easy! The molds lift effortlessly out of the bin, and getting the ice cubes out of the mold was as simple as pulling them apart. The ice cubes did come out crystal clear! The tray itself is not very large and doesn't take up a large amount of space in your freezer.In response to all the reviews that said the ice cubes were too small: just read the item description. It says they are 1.375 inches square, and they are. There are larger ones at 2" square, but I intentionally bought these because they are easier to fit in a tall, skinny glass like a Collins glass.

This does make clear ice cubes though I thought they would be bigger. I mostly make drinks in double old fashion glasses and having to use two cubes (one looks a bit silly) consumes the cubes faster and dilutes the drink a bit more than one cube would. The need for two makes me fell like I'm constantly making cubes and wondering if the clarity is really worth it.The cubes release well and I put them in a bag so can clear things away as there are a lot of pieces laying around if you don't.After about four attempts, I think I figure out a process to get it right but it is still messy and waists water and energy. After I empty the trays, I'm left with the ice in the bottom of the inner tray that needs to be removed. The fastest way I found to remove it is to set it in the sink (I have a smaller sink in my bar) and fill the sink and the tray with hot water until the remain ice melts enough to separate. Once empty, I take a 1 cup spouted measuring cup and fill the inner tray sections up to the third line from the top, then slip the silicone forms back into the tray. I had to do this in the order because, when I put the forms back in the tray and filled them with water, I partially got bubbles in the ice or less than square cubes. By having the water in the tray first, I solved the problem but it does make a mess as it is really hard to pour into the inner tray sections to the exact right height. After I clean up the counter and the tray top from the water that was pushed out, I take the measuring cup and a teaspoon and slowly fill each form to the top of the form so I will get the "square". If I overfill, I use the spoon to take out some of the water in the form to get it back down to the right level. I put the tray back in the foam hold and place it i the freezer drawer in a place I have cleared out, permanently for that size piece.Because of the effort and room consumed in the freezer, I'm not aren't considering the larger version.Again, the results are nice, square, clear cubes as promised. Just wish it more convenient. It would have rated it higher if that was the case.
