I believe that if u were to boil it and then leave it in the water till it came to room temp it should be just fine. The problem with boiling is that if u heat it up and then cool it down really fast it stress the glass and causes it to break much easier. This is my opinion on boiling but i believe that rubbing alcohol and kosher salt works best on glass.
