melodious fellow Reviewed by melodious fellow on . boiling glass hey everyone, i need some pointers on boiling glass parts to clean. i have a pretty thick bowl/stem that i just boiled. this got it alot cleaner than just trying to clean it by hand. (i dont have any rubbing alcohal) ive broken plenty of glass steak plates. so my question is will it break? is 420 glass high quality pirex? ive heard something about adding salt to the mix. stoned in the kitchen:D peace Rating: 5
