Er zijn natuurlijk diverse methodes om te "bruneren".
Een ervan vond ik op het Web, wel in het Engels:A beautiful rich deep brown can be achieved on copper by using first the liver (correct name: Potassium Polysulphide)which is available from most chemical suppliers.
It comes in the form of solid dry stones which are easily dissolved in water.
One small stone, about the size of your smallest fingernail will be enough to mix a solution of 600 ml.
Put this in a spray bottle and apply to the copper while consistently heating with
a gas torch. Then gently rub down the surface with a wet scourer(schuursponsje) until you have an even light brown colour.
Then reheat the surface, this time applying a weak ferric nitrate, this will richen, redden and darken the brown that you achieved with the liver, when you are happy with the colour, coat the surface with either a wax (floor wax is sufficient) or clearcoat.En Ben, hier wordt dus duidelijk gebrand.
Groeten, Wil
