Etch Pyrex? Are you insane?
Do you literally want it to break?
checks username
Ok, carry on..
I've seen it done, does etching cause weak points? The modern crap. Can't etch borosilicate.
Hasn't broken mine. Despite the other person saying I'm trolling... Sometimes I am... but not this time. I have old school pyrex stuff and I used a small carbide drill tip and just scratched the marking for ¼, ⅓, ½, 1. Worked fine. I didn't write any numbers or anything just a small scratch. The numbers are already implied so whatever.
Interesting. Guess I'll have to take your word on that. 🤷
Yeah when I said etch I should've just said scratch i suppose. I wasn't recommending you pull out the Dremel and copy it one to one. Just small cosmetic scratches. Or you can look around at antique shops, I find stuff like that all the time for cheap.
Acid etching is a thing, too. Not likely to shatter the whole thing using acid.
As right as you are about acid etching, you still don't wanna fuck with glass that's designed to handle torch temperatures..
Edit: Also, don't they literally use pyrex in chemistry labs to handle acids? What acid even eats proper borosilicate pyrex glass?
Hydroflouric acid etching cremes are supposed to be able to etch borosilicate.
Cool. I'll have to remember not to clean my weed pipe with said acid. 👍
Wait, that reminds me, I still have weed!
But do I have a working lighter..?
Yes it releases the tension within the glass, and I think it's still heat tempered glass even tho it's not borosilicate - meaning it would crack once you broke the surface.
If you aren't putting it in the oven then it should be fine right?
Laser etching glass is a thing
Yes, and laser etching metal is a thing as well, which changes the material's temper, glass or metal, creating a potential weak point.
