I like the thermal mass of glass for temperature stability, as I’ve found that’s pretty key to getting good print adhesion. But I really wanted to try out PEI without having to stick a giant magnet directly to my heater plate, something I definitely did not trust.
Turns out, you can solve both problems! This was how I did it.
glass is at least as- if not more- recyclable than metals. all you really have to do is remove the adhesive film- the plastic is what makes it not recyclable, and that’s true of the metal plate as well.
Literally no one takes sheet glass here for recycling. Bottles, yes. Sheet glass, no.
I can throw all metals in with curbside metals recycling.
Therefore, for me, metal is recyclable and sheet glass is not.
