Glass Should Not Be Put In Direct Sunlight
I am asked on a daily basis why does your glass pieces say no direct sunlight? It says that because when glass is put in direct sunlight it makes prisms and prisms can start a fire. Kind of like a magnifying glass. It's mostly applies to pieces with a lot of clear glass. Clear glass makes the most prisms. Do not put your glass not just my glass in a window or on a window sill.
