As usual an Internet search seems inconclusive.

Just in the process of throwing out all the bits of the old cooker hood

Not sure that it is chemically different. There is an alternative
hardening process which diffuses potassium into the surface (roughly
analogous to carburising or nitriding)

But IIRC you are not encouraged to recycle any sheet glass into bottle
banks.

yup, iirc they don't take it. Freegle/freecycle it.
