The Turquoise Patina I use is a hand-made natural patina on Copper. The colour is produced from the reaction between the copper jewellery and the vapours of sea salts and ammonias (like vinegar). The effect is similar to the green copper roofs on the parliament buildings in Ottawa, or the blue copper on the buildings by the ocean in Nova Scotia.
Additionally I buff on a thin layer of conservator’s wax to add additional gloss and protection.
**This patina should avoid soap, water, and chemicals to maintain its dramatic colour.
