Hematite Brünierung für Eisen 5 KG

Hematite is used for blackening iron. The process is odorless, can be done at room temperature and you do not get black fingers. The burnishing process can be stopped at any time. You can use Hematite undiluted or diluted 1:3 to 1:5 with tap water to prepare a burnishing bath. To be sure that the surface is free of acids, the draining water should be tested for neutrality with an indicator paper.
