Fireplace blackening procedures?

WE are looking for know-how, equipment and chemicals to blacken steel made home fireplaces. We just want our products (fireplaces for homes, 40 x 60 x 1200 cm size appr.) to look black and to stay that way!

Dear Mr.Maric,

One answer is that the cheapest process to blacken your steel home fireplaces is the so called "black oxide" process which is a hot (140°C) alkaline (caustic) treatment. You will need a treatment line including tanks for cleaning- flow water rinse-acid pickling-flow water rinse-black oxide-flow water rinse-emulsion oil. There is also another process for luxury articles including bright nickel plating and plating of a gray-anthracite nickel alloy, but more expensive.

I bought and installed a free-standing wood burner ('The Earth Stove') myself just last week; it's really a very nice stove, but ...

It was painted black and came with instructions for how to do the required 3-stage 'burn and cool' curing process. It was a total pain in the neck, with the stove unusable for three days, and the house smelling unbearably like an insecticide factory for those three days plus a few more days as the paint cured under heat.

By all means, market your line with a black oxide finish rather than black paint!
