The pic is part of a box I’m building to try out a few new inlay and finishing techniques. The finishing part has been a PITA. I’ve used Copperas (ferrous sulphate) before on White Oak, and it turned out a nice, even gray – very pretty, actually. So I thought I’d see what it did to Cherry… not so nice – kinda blotchy and inconsistent. It’s an interesting look, though. The problem I have is the odd, white areas you can see. I didn’t have those on the oak table I did. I used a spray lacquer on the oak table (I had access to a spray booth then) but am brushing shellac on the box.
Any ideas what would cause shellac to do that? It might be a reaction to the chemical stain (in which case I might be out of luck), but maybe it’s something simpler. It has been very humid and hot in the shop lately.
I’ve tried to gently sand it down a bit and recoat (I’ve put on about 3 or 4 coats of 2# blonde shellac), but it shows up in the same areas again.
