Copperas limewash is now my favorite substance (at least of those which don't contain ethanol). A sample arrived this morning in a small pot. This milky, pale green liquid, when applied to lime stucco, turns first to a deep orange and then, on drying, to a subtle warm orangey-cream stone colour. The pigment is Ferric Oxide I believe and it could have been the very same that was applied to my house when it was built in 1840. It's too dark to take them now, but pics will follow.
