Is it safe to heat, cool, or freeze glass?
It is safe to heat or freeze our Boronex®toys. Heating is simple, from, running it under desirable water temperature to, acquiring the smallest plastic container that you can lay the toy in and pour hot water just over the top of the toy. Be careful not to over heat the toy. A micro wave will only heat the water not the glass. After just two minutes the toy can be removed, dried, lubed and WOW. It can be left in the water for up to another 20 minutes and still have great deep heat. Always hold the toy in your hand for a moment to test the temperature. Cooling and freezing are safest with “CLEAR” Boronex® or solid,” CLEAR” borosilicate glass. Recently we spoke to many very satisfied customers and found that most of them had not tried to heat a toy. Were they just complacent with cold toys? No, they were still enjoying the smoothness of glass. Later we heated up a few and watched their eyes roll. Oh well, still more to discover about glass.
