Best source for ground glass

[2F/2F]

What I want is a good-quality one made of some sort of plastic material instead of glass (for my field cameras). Is this possible?

Plastic may be possible as all GG for microscopic cameras (read 135 size film) are made of plastic. Unfortunately those plastics are so soft they scratch really easily !
But in those cameras the GG is well concealed. So it can resist very well scratching. what a bout a big 8x10 GG without protection ? how long will it be usable ?
Just my 2¢ ;-)

Tachihara ground glass (plastic) screen/fresnel + gridded cover glass is a good one.

Bruce Wehman's 8x10 camera comes with both glass and plastic ground glasses. I tried both and decided that while the glass one was a little brighter and a little clearer, the plastic one (it may have been plexiglass,) was 'good enough' as well as lighter and, of course, not really breakable. So yes, it is possible.
