About the Metals:
Silver: I use Sterling silver – Sterling is 92.5% pure silver.
Brass & Copper: I use solid brass and copper.
Gold Filled: Gold filled is a layer of gold pressure bonded to another metal. The weight of the gold is 5% of the total weight of the metal, and it is much more valuable and tarnish resistant than gold plated items as the gold doesn’t not flake or rub off over time, The metal I use is 12k Gold Filled.
Gold Foil: Keum-Boo 24k gold foil is 25 times thicker than gold leaf, and can be fused to silver as decoration.
Cleaning your jewellery:
All of the metals above will tarnish over time and with humidity or water.
You can buy metal polish from the supermarket or hardware shop to keep your jewellery shiny - for example Brasso or Silvo. There are also some home recipes for cleaning brass and silver jewellery available online.
