Is fiberglass food-safe?

Even with multiple layers of polyurethane, I should think not. If the fibers escape, they’d not be good to ingest. It’s just too risky, in my opinion.

Well a quick google suggests that there is such a thing as food grade fiberglass. So it probably depends on what type of fiber glass and which resin you use.

Tons of minuscule slivers of glas? Sure, why not?

@Lightlyseared has the right idea, but it’s probably hard to get.

A mesh of fiberglass? Um… no. You want stainless steel or wood covered in cheesecloth.

Oh, look, I found a website: http://www.aces.uiuc.edu/vista/html_pubs/DRYING/dryfood.html#methods

Wood slats or stainless steel screen mesh are the best materials to use for the racks. Cake racks or a wooden frame covered with cheesecloth or other loosely-woven cloth can also be used for drying racks.

Stainless steel seems to be the modern way to go. You need the Foxfire books @incendiary_dan.

Well, here I was hoping someone would tell me it was okay and the fibers don’t really come off often enough. Shucks.
