Dexas Ice•ology Clear Ice Maker Tray for Crystal Clear Ice, 8 Square Cubes BPA Free Silicone Clear Ice Cube Maker, Craft Ice Cube Molds for Cocktails, Drinks & Whiskey, Gift Ideas

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.

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.

This maker makes fairly clear ice in my chest freezer but not perfect. I have a 4 ball round cube maker that makes absolutely clear ice with hot tap water but it takes 48 hours. I believe the key to getting crystal clear ice is for the cubes to freeze slowly. If your freezer is 0 degrees, it will freeze fairly fast and be cloudy. If your freezer is set warmer, I think I get better results. So if you have a freezer with digital temperature control, turn it up to as warm as it will go and try it if you aren't getting good results. This does work and cubes are fairly clear, and I like the size of the cubes for cocktails.

This is the easiest system for making clear ice cubes that I've found. The cubes come out perfectly clear, and filling and emptying the tray is almost as easy as a normal ice cube tray. Be ready to do a little more work than normal, as each individual cube is made in a mold, so after you've put the unit together and filled it w/ water, you'll need to be ready to work a little to get the ice out. The cubes are easy to retrieve, although you have to break the clear cube off from excess ice and bubbles etc. that form in the water below the cube molds. Before using again, you'll need to get the excess ice out of the bottom part of the unit, which behaves like a large conventional tray into which the molds for the clear ice fit. It's all a little extra work, but the excess ice also comes out in cubes that you can use for cocktails where clear ice would be a waste of time.

Important: Make sure you let them warm up to room temp each time you go to put water in them and freeze new ice spheres. If you do not, then you will not have clear ice! These work great if you follow those instructions. It is about the speed of the freeze!

This is a well made product. Parts fit securely, and it makes an awesome cube with sharp edges! But totally clear ice? I followed their directions 100%.The reality is it's not possible to make clear ice using a regular freezer like you and I have. A regular freezer with a temperature around 0 degrees Fahrenheit will freeze ice too fast and trap air.I've tried all the tricks: boiled water (cooled); double boiled; filtered; distilled; straight tap water; warm water. I've insulated this insulated device in another cooler to keep it warmer (didn't help). The freezer is just too cold and freezes too fast and the ice is not ABSOLUTELY clear. It is FOR SURE clearer than normal freezer ice, but not the crystal clear all the way I was hoping for.Maybe there is a hidden technique out there to make it totally clear. Or else I need a mini freezer I can muck with to set the temperature closer to 28 degrees F and slow down the freezing process.UPDATE 09.18.21 - I did end up buying a mini freezer AND a remote thermometer, AND a smart controller that can turn the freezer on and off so I can control the internal temperature pretty closely (on the order of +/- 2 degrees F). The result is much clearer ice. It's a fun thing to do, and it works way better than your standard freezer could ever do. As far as this product goes, it has been very durable, very easy to use, and produces nice ice cubes. I would buy it again - then again if you do buy it, realize you may need to buy the mini freezer, thermometer, smart controller, etc. Sigh,....
