ANCIENT BRASS ON BRONZE

This is a hot flame process involving several chemicals. Also a compound process whereas one color is the base then the second layered in uniform areas on top of the base color. This finish is another original Chisler M.F.G. Co. Development and one of my best. Through chemical processes the reddish bronze becomes old tarnished yellow brass. Then there is a red oxide layer distributed in uniform areas covering about %50 of the surface. This compound finish combined with a heavy texture becomes a true artifact. It looks unquestionably hundreds of years old. A lot of hand work is involved in this finish to remove just the amount of oxide layer to give it that ancient artifact appearance.

ANCIENT IRON ON BRONZE

This is another compound patina developed at C.M.C. This finish starts with an actual layer of steel impregnated into the surface of the bronze. Then the steel layer is darkened to look like old worn iron. On top of this steel layer a hot flame chemical red oxide layer is applied, this layer has to set for several days. Then the piece is high-lighted leaving a 50/50 balance of old iron and red oxide. The affect is that is iron that has been out in the rain but well handled for many years.

BROWN RUST ON IRON

This is another two part patina. Although not as difficult as some of the others, it by far takes the longest time to produce, about one month. The bail is repeatedly dipped in salt water and allowed to dry and rust hundreds of times. When a good thick layer of natural rust has been achieved its on to the next step. Then a combination of sodium nitrate, nitric acid, and potassium chlorate are hot flame applied. The result being a maroon dark brown.

BLUE STEEL ON TEXTURED WHITE BRONZE

The white bronze appears identical to nickel. It doesn't take many patinas, because it only has about % 60 copper. To cover this metal kind of defeats the purpose of seeing the white bronze. How ever there are a few finishes that are worthy on this metal. First the metal is heavily machine hammered, then the blue steel process applied and removed. The result is a white bronze with dark black down in all the impingement's (dents). This metal when treated with other chemicals can produce a nice gun metal gray. Although this finish is not quite as durable as the others it still has merit.

RED OXIDE ON BRONZE

This finish is produced by combining ferric nitrate , potassium dichromate,and ferric oxide. Then its color can range from light red cream coffee to a dark creamy brown depending on how and if it is waxed. I usually use past wax on this finish. Its a great looking and durable finish.

HIGH-LIGHTED RED RUST ON TEXTURED RED BRASS

This is what is referred to as a transparent patina, you can see threw it, it is in a sense a colored filter for the metal beneath. I would describe this color as a mixture of clear red, light brown and orange. The intensity of the color can range from light to dark depending on your preference.

RAIN BOW GOLD ON BRONZE

This is an interesting and subtle finish produced with sodium oxide. It turn the reddish bronze into a golden yellow, with all the colors of the rainbow on top. This patina would probably have to be protected from the air with lacquer to retain its original bright yellow appearance. How ever the ones I have had for over a year with out lacquer have a nice look of there own. Though darkened by surrounding air they still retain their rain bow colors.
