A friend of mine is trying to restore old 30x40cm (~12x16") camera from around 1900. He is very experienced LF camera builder.
On this camera he found unusually bright (even in corners) ground glass with super fine texture, yellowish in colour. Glass already had some clear spots but when he tried to clean it with wet cloth, ground glass texture started to melt/dissolve and become transparent. He did try to replicate it with eggs white, shellac and gelatine but he can't replicate fine texture of it. Does anybody knows what secret ancient emulsion was applied to this ground glass?
Thank you in advance!
