These little studs are perfect for every day. Just the right dimension, and the perfect weight. Your choice of patina'd bronze, yellow bronze, pink bronze, or sterling silver.
Patina (/ˈpætɪnə/ or /pəˈtiːnə/) is a thin layer that variously forms on the surface of stone, copper, bronze and similar metals (tarnish produced by oxidation or other chemical processes), wooden furniture (sheen produced by age, wear, and polishing), or any such acquired change of a surface through age and exposure.
My process of applying patina onto copper has been an ongoing development since my time at NSCAD. Now mostly I use ammonia and salt, and put the pieces in a contained space for at least a 24 hour period. Some times I take the pieces out and put them back in to deepen the patina even further. Afterwards the pieces dry out for at least half a day and then I apply a fixative to ensure it stays in place. I then highlight the edges to expose the metal from underneath and do one final fix/ spray after that.
The coloration of patina very much depends on season- humidity, sunlight, temperature etc. From experience, I see a brighter blue in the summer and darker blue in the winter.
