Dipping and brushing blueing stain 1 liter

The term "browning" comes from the word "tanning".
This also includes the blackening, which is mainly used for ferrous articles at a temperature of 300° C or higher. And because this method is far too complex and dangerous for normal domestic use, a so-called brush burnishing, which can be ideally processed at a temperature of 12 to 25° C, is used here.

Many items made of brass, copper or bronze become unsightly over time and need to be reworked. This includes, for example, lamps, candlesticks, lamp bases, vases, handles, candlesticks, figures, fittings and much more.

The partly spotted or soiled surface is first cleaned of dirt and dust adhesions with a common household cleaning agent. This is followed by rubbing with a cloth moistened with solvent to remove paint residue, oil and grease. The item is then carefully sanded down on all sides with fine steel wool (e.g. our reference 334833, 345949 or 334834) in such a way that the original metal color is visible again over the entire surface.

Only then does the burnishing follow.

To do this, the object is thinly painted over with a soft brush soaked in immersion and brush bluing stain. The stain adhering to the metal surface is moved with the brush until it changes colour. This starts with light brown, goes to a medium reddish brown, dark brown to deep black. If the desired color appears, the object is immediately held under running tap water, which stops the browning. If this moment has been missed so that the part has become too dark, this can easily be corrected again: To do this, it is rubbed down again with steel wool and then blued again.

After drying, the surface is rubbed with an oily cloth. This prevents further oxidation (browning), which can happen due to humidity. When processing this metal stain, protective gloves and goggles must be worn, which you can also find in our shop.
