Our Metal colouring Antiquing fluid / Patination fluid is used for the colouring and aging of Copper, Brass, Bronze, Pewter etc. It is fast, effective and etches the colour onto the surface of the metal. Our Black Tourmaline, leaves a nice dark finish, for a slightly lighter finish please see our Brown version.
By a simple technique metals can be coloured with a layer of oxide, a few micron thick to provide an antique-like finish.
Remove any metal lacquer using paint stripper or similar solvents. Thoroughly remove and clean any grease or oil, including fingerprints.
Apply the Antiquing Fluid directly onto the item, using either cotton wool or a brush, and watch the surface quickly change colour. When the desired colour is achieved, rinse immediately with clean water or weak alkaline solution and pat dry with a cotton cloth. Alternatively, dilute with 10 parts water and immerse item to ensure a uniform colour change, this process is recommended when treating more than one item. Apply some agitation to prevent high spots caused by tiny air bubbles. After treating, items can be sealed with a wax, oil or lacquer.
Please Note – Not recommended on Steel.
It is always recommended to test a small area first.
