B/OX 311

15% to 20% by volume solutions produce black to blackish-brown US 10B finishes on copper and brass with immersions of 1 to 3 minutes. Diluted 5% to 10% by volume solutions produce lighter flemish and statuary bronzes with 1 to 3 minutes of immersion. Desirable underlying red tones revealed upon highlighting the brown tones.

B/OX 312

20% by volume solutions produce more pronounced brown to chocolate-brown colors on copper and brass than 311, with a richer reddish tone when highlighted. 1 to 3 minute immersions. Desirable underlying red tones revealed upon highlighting the brown tones.

B/OX 313

Used at the same dilutions as 311 and 312 with copper and brass, but the highlighted finishes do not exhibit any underlying red tones. Also used to blacken silver and nickel.

B/OX 314

Similar in action to 312 but slower acting while producing warmer and richer brown tones of varying intensity to include deep walnut browns on brass and bronze.

B/OX 315

It has a very wide operating window in regard to concentration to produce light brown to chocolate brown colors on copper and brass. It does not produce as much smut or rub off as other oxidizing solutions. Concentration is 10 to 20% in water.

B/OX 316 GEL

Immersion or swab-on verdi-green color that is used 50-100% by volume. It can be applied directly to properly cleaned brass and copper. Results in a thick verdi-green finish that accepts lacquers and powder coats.

B/OX 316

A natural verdi-green is produced on copper and brass with immersion times of 1 to 3 minutes. Liquid concentrate is diluted with 3 parts water. It is applied over B/OX 311.

B/OX 316 and B/OX 318

B/OX 318

A ready-to-use oxidizing solution that produces a rustpatina (orange-yellow-brown) oxidized appearance on copper and brass. Rust patina used at 100% by volume sprayed or dipped.

B/OX 324

An instant acting swab-on/touch-up chemical conversion finish for copper and its alloys. Color can be varied from light brown to brown-to-black.

B/OX 325 and B/OX 327
