Re: Scalding with bottle warmer - bottles keep cracking!
Are you letting the scalded glass bottles cool completely before using them? And when you take them out of the bottle warmer, are you setting them on an insulated surface, or directly on a cool countertop? Temperature differences can cause cracking in heated glass because the surface of the object- in this case, a bottle- that is in contact with something cold (e.g. a countertop, cold or cool milk) will cool and shrink faster than the part of the object that is in contact with the air.
