BRASS ANTIQUING PROCESSES

DARKEN BRIGHT BRASS TO A DARKER BROWN

Blackfast 183 will darken bright brass surfaces to a dark brown. The bath should be maintained at a temperature range of 35 – 40c for the best results.

At lower temperatures, the process is slower and the recommended immersion time of 5 minutes exceeded.

On removal from the solution, the brass is allowed to dry then lightly abraded to remove some of the coating on proud surfaces. What remains will be within the crevices and surface of the brass revealing an antiqued surface.

STEP 1

Components must be free from grease

STEP 2

Water wash to obtain a wetting condition

STEP 3

Immerse in Blackfast 183 until brass reaches the required shade of brown. Dilution 9 parts water to 1 parts Blackfast 183. Average dwell times: Brass plated items – 3 minutes
Brass – 5-10 minutes

STEP 4

Water rinse

STEP 5

Dry components – methods available:
i) maize
ii) oven dry
iii) hot air

STEP 6

Relieve components if a contrasting effect is required – methods available:
i) rotary vibrating machine
ii) typhoon barrel
iii) manual clean with abrasive paper/cloth
iv) polish using a rotary bench polishing machine

STEP 7

Lacquer finish if required
