A place to share practical, durable and quality made products that are made to last, with an emphasis on upcycled and sustainable products!
Guidelines:
Things that are well-made and durable (even if they won't last a lifetime) are A-Okay!
Unlike that other BIFL place, Home-made and DIY items are encouraged here, as long as some form of instruction is included in the body of the post.
Videos links are not allowed as post titles, but you may use them in a text post.
A limited amount of self-promotion is accepted, IF the item you are selling aligns with this criteria:
- The item must be made with sustainable or recycled materials.
- If electronic in some way, the item must be open-source.
- The item must be user-serviceable (if applicable).
- You cannot be a large corporation.
- The post must be clearly marked with a [Self Promotion] tag in your title.

I would just etch the glass while it can still be read then you're good forever
Etch Pyrex? Are you insane?
Do you literally want it to break?

Ok, carry on..
Laser etching glass is a thing
If you aren't putting it in the oven then it should be fine right?
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.
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.
