Each nICE mug kit will be shipping with clear (cough, cough) instructions on how to make long lasting nICE mugs. The cough cough is because long lasting nICE mugs are directly relative to being able to make clear ice.
Clear ice can be tricky business. However, I have tested and perfected the process of getting water to freeze clear in the nICE mug mold.
Though nICE mug welcomes tricks and tips on getting water to freeze clear, we have extensively tested such things as:
2. Reverse Osmosis.
3. Filtered Water.
4. Holding one's breath and drinking 16 oz. of water. Oh, wait, no, that's for hick ups.
But seriously, here's the deal. Those of us from cold climates, like here in Minnesota, may have had the fortunate experience of ice skating on a freshly frozen lake. Nature provides perfect ice under perfect freeze conditions. Lakes don't freeze clear because they were boiled twice, or sent through a reverse osmosis machine. Clear ice happens beautifully, during dry, cold, calm winter nights. A thin layer of ice covers the lake, then layers build down from there. The nICE mug mold "tricks" your freezer by replicating this natural freeze process.
I can tell you more, yet there is more clear ice chatter to come on www.nicemug.com.
