Thank you! :thumbup

I do. I make these out of borosilicate (Pyrex) glass. Not your typical wine glass. I do some beer glasses also, these all hold 16+oz

Holy fuck, you made those from Pyrex? That is AWESOME. I am curious, do you make these for sale or just fun?

Thank you! I have a lot of fun making them but I’m trying to make a full time career out of it after 10 years of after work and weekends.

What do you do with your glass scraps?

I attended a beach glass festival in Cayucos,
One of the vendors had blown glass scraps that they found tumbled on the beach.
I guess a glass blower donated his scraps to the ocean to work the magic.
The bright colors and shapes that go into paperweight glass balls, are really something as beach glass.

Please don't throw glass in the ocean.

Definitely not.

I recycle my glass, but no recycled glass will ever be glass again. COE, or coefficient of expansion, is what defines types of glass. I use 33coe, borosilicate. Meaning it expands .000033mm for every 1 degree Celsius increase, same way metal expands before it’s liquid hot (don’t quote me on the amount of 0’s) It’s a blend of mostly silica and boric oxide among other things. High melting point and low COE. Most glass out there is “soft glass”, or soda lime, made of silica, sodium carbonate, and calcium oxide, with a COE of 90-100+. Lower melting point, longer working window. Glass with a lower COE expands and contracts less with changes in temperature, which is why people like Pyrex dishes, particularly the old ones, as they were borosilicate with a COE of 33 where as these days the name has been sold and Pyrex dishes are no longer boro, they have a COE closer to 90 and they can’t take sudden changes in temp like from oven to cold counter or whatever without cracking. Same reason any lab equipment is made of borosilicate or quartz. Long story short, you can’t blend unknown COE’s and make usable glass so any glass you recycle will end up as sand and or components for asphalt/concrete kinda stuff.

My mom was a chemist and had some pretty neat glassware I got to wash as a summer job. I heart condensers.

Surprisingly this isn't a bong...
