I'm Wet Collodio Photographer in Italy. I've started to make handmade and custom made ground glasses. I make them with the finest oxides powder and I do the finest grain. I can make ground glasses in all your sizes. Thick. 2mm glass.
Ok... It's a start, so the price are really low. Shipping only to Europe.
I ship the glass into a sandwich of plywood, paper and soft material.
Ask me for prices. Thank you for your attention.
