Local Source for Borosilicate Glass?
Hey there, I'm a beginner glassblower and I'm looking for any local source of borosilicate glass, my issue is that U.S. pyrex isn't really boro like
it's supposed to be, it's soda-lime and it pops and cracks on any contact with my torch.
I could literally use any source, such as a bakeware that's actually borosilicate and not something else, can be in any shape even if it's a dildo
although this will not be fun to buy, and yes I've already tried synthesizing it myself but boric acid is very dangerous and I'm waiting on a
respirator order to get here.

I have some broken Pyrex labware which is real borosilicate glass if you just want stuff to practice on. I gave one guy a whole box of broken
glassware to melt down years ago, but I have a little bit more now. Plus I have a few items that might be repairable. Do you have access to a
proper glass blowing torch and annealing oven, or are you trying to do this at home?

What's so dangerous about boric acid? I use that all the time and it's fairly benign - only a 1 health and reactivity hazard. Just wear gloves, and
maybe one of those white dust filter masks if you're concerned.

Boric acid? Dangerous? I guess almost all chemicals are dangerous to some degree, I just would not go eating the stuff and wear gloves and wash hands
when done working with it.
I have always thought of it as fairly safe.
I have some broken glassware as well. Some pieces are thick.

I am doing it at home, but i've got a DIY kiln and a 6B national torch, along with the tanks, I have everything practically,

That's pretty impressive. If you want broken pieces of Pyrex, I think you can get some from someone here, mostly depends where you are located, as
the shipping might get expensive, unless you just want pulverized shards, which fit easier into a flat rate box.

Oh nice, what kind of pricing would you put on that boro, organicchemist25?
I found out I probably won't be making my own glass because the recipe says 800 degrees Celsius for 12 hours lol... I can't sit next to a kiln all day
and risk setting my house on fire, it's also more expensive and way harder than just buying the boro already chemically formed.
