CRD The Use and Application of Epoxy Resin vs Vinylester vs Polyester (1).pdf

You guys are right. I had to read that about 10 times before I could wrap my head around the way it was laid out, not that it was incorrect!
I always though that was a screwy resin to glass ratio

And all this time I thought it was me:)

I was on the verge of making a glass bow and decided not too:)

I mentioned that Gordon and Bjorn use Vinyl ester in their glass and that BP use epoxy. I found this explanation which in an understandable way explains what they are. Maybe of interest.

Good info, thanks Bue. Do you have a link to the Bjorn glass manufacturer?

Flem. Last time I ordered glass from them I used this email adress, [email protected] They only make glass for special orders. Their main business is other things. I know they make FITA paper targets and arrow vanes. They are kind of a dark horse, I do not know of any web page that advertise their products. They were much bigger on glass before when Earl Hoyt and others used their glass.
