thickness of glass for sinks

Deb DeForest · Post by **Deb DeForest** » Wed Nov 12, 2003 7:34 pm

Can anyone tell me what the most common thickness of glass is to form a sink? I'm using 3mm BE glass -- I'm thinking it should be about 12mm thick before slumping into the stainless mold. Any comments? Also, any advice for fusing 4 layers of glass and special problems I should be aware of in advance?

Thanks,

Deb

Hey Deb. There is tons of info about sinks both in the old and new archives. Do a search on sinks. While 3mm is probably too thin, you probably don't have to go as thick as 12mm -- but you could. Just remember when fusing that glass wants to be 6mm thick so you will have to dam the piece. BE has information about annealing schedules for thick pieces on their website. Have fun!

When I'm using 3mm glass, I make the blank 6 layers thick. My goal is to start with 3/4" thick glass (or as close to it) before slump. - Barbara

Like Barbara, I also want 3/4" as the thickness for sinks. Thicker can be great also, just have to think of what look and use of the sink you are going for. For an oval sink a drop mold works well. You need to know your glass and when the flow of the glass is not quite touching the bottom - need to flow slowly also so the neck or inside of the drop ring doesn't get thin or have stretch marks. After the slump the sink can look stunning by cutting off the lip then polish to a high polish.

20mm is my goal as well. I fuse 2 layers of 10mm and let them spread a bit.
