Collar filigree, triangular filigree, brass stamping, raw brass, unplated brass, US made. Raw brass findings are the most versatile stampings that we carry on this site, because with a little ingenuity you can make them your own. One way to add a quick, non toxic antique finish is to soak them in a vinegar and sea salt solution for an hour, then bake in a 400-425 degree oven for 15-20 minutes (ovens vary so you may have to play with that.) They will come out a lovely brown color. You can buff them a little if there is too much darkening in some spots. When cool, seal with brass wax OR what I like best is to seal with MATTE spray lacquer, found in hardware and crafts stores. Check out Swellegant, Ink Paints, Alcohol Inks, all sold here at B'sue Boutiques. You can really make raw brass your own signature look! 37 x 40mm. Sold by the piece.
