Has anyone ever tried to engrave on a wheat straw tray or any similar products? Is it safe to do so? And if so, will the item remain food safe?
I want to make a Santa Treat plate on this tray (linked above) but I can’t find any information on if it is safe to do so or not. From my research I have found that some wheat stray trays are fully biodegradable and food safe and some contain plastic add-in (still food safe). But the element of engraving on it (and it still remaining food safe) has been harder to answer.
Anyone have any experience with a product like this or similar?
Food safe? Almost no burned plastic is going to be food safe. There are a lot of nasty byproducts to burning plastics that I wouldn’t want to ingest.
As for glowforge safe, this plastic add-in is the question. Without knowing exactly what plastic it is you’re taking a risk that it might contain chlorine or other ingredients that might form vapors that could harm your glowforge. I’d try to find out exactly what plastic (resin) they’re using and go from there.
