On copper alloys, gray to black develop, gunmetal blue patina and light purple patina; on white metal\/silver\/tin predominantly browner tones.

Dilute 10 to 20% with distilled water<\/a>. Example with 100 ml concentrate:<\/p>\n Build color in short cycles for better control over transitions and intensity.<\/p>\n <\/p>\n <\/p>\n Patina is controlled surface chemistry. Material type (copper, brass, bronze), pre-treatment and mixing ratio determine the colour family. By sealing, you capture the result and make the finish more resistant to touch and environment. <\/p>\n The process for our patinas is similar. Take a look at a quick example on brass: <\/p>\n\n
Apply Gunmetal Blue & Purple Patina<\/h3>\n
\n
\nClean the metal completely and free of grease. For galvanised layers: rinse thoroughly with cold water and activate briefly with a light acid or
\n patina fluid<\/u>Immediately after rinsing, dip the object in the patina liquid. Move the parts around to avoid air bubbles and contact everywhere. <\/li>\n
\nRinse the object well. If necessary, immerse in baking soda dissolved in water to neutralize the remaining acid. <\/li>\n
\nFor color retention and abrasion resistance (especially when touching\/outside): seal while the surface is still wet from the rinse.<\/p>\n\n
