Barrel browner,
How long do you leave the barrels to rust? I say I get a decent layer of rust after two hours in a humid and warm bathroom. It might not be deep enough as I leave them for only a couple of hours, but I am afraid I will cause deeper rust pits with a prolonged exposure. Before I hang the barrels in the bathroom I let the hot water shower on so that I have plenty of humidity and the heat on, for 75-80 F.
Stallones,
So you boil only once at the end, for a black and white pattern?
Is your etching solution full strength as it comes out of the bottle?
I have some logwood powder that I boiled the barrels once after a few applications. I used two-three tablespoons in a gallon of water and it seemed too strong a solution. I let the barrels soak in for 5-6 minutes and it came out blotchy. When I lifted the barrels after a minute or two in this solution they seemed evenly coloured. I am planning to put less logwood powder as it may be stronger than the whole pieces of wood and boil the barrels for less time, maybe 1-2 minutes. I did not use the Ferrous Sulfate in the logwood bath, maybe I should.
