Safety Disclaimer-Warning

Handle glassware with care & wear goggles & gloves because:

1. Unless you poured it yourself, assume any liquid is hazardous.
2. Hot & cold glass looks the same & does not have to be red to cause burns. Unless it was in the freezer, assume it is hot.
3. Borosilicate glass will withstand a fair degree of thermal shock but unless your intent is to see if you can make it crack, don't toss recently heated glass into a cold water bath.
4. When borosilicate glass breaks, it makes sharp edges like any other kind of glass. Dispose of pieces carefully.
