Cyanotypes on Glazed Ceramic Tiles
I was looking for some advice on sizing ceramic tiles for cyanotypes and came across Photo Engineerīs APUG recipe:
10 g 250 BI photo grade gelatin
90 g Distilled Water at RT
Mix and gradually raise to 40 deg C.
Add 5 ml of 10% Chrome Alum solution.
Add a suitable wetting agent if needed if tests show problems coating.
Spread on clean, grease free tile at about 10 - 15 ml / foot square.
Allow to cure for about 1 week.
Has anyone tried this successfully? Is it possible to do the same using some kind of varnish instead?
