Today's Word: CRYSTOLEUM
The crystoleum (chromo-photograph) was basically an albumen photograph placed face down on a concave glass and the paper backing removed, leaving only the emulsion stuck to the glass, which was then made transparent by using a wax or oil, and when only the outlines were visible, the once-photo was partially hand painted. Another curved glass was placed behind the first glass (and the partially painted picture), and larger parts of the painting were then filled in on the second glass. This double-glass painting created an almost 3-D image. Crystoleum-making was popular in England from the second half of the 19th century till World War I, and while many were produced, only a few survive.
