Materials
Robin uses many different types of materials including stones from all over the world.
Metals
- Gold
24 ct, pure gold
18ct, hallmarked 750
9ct, hallmarked 375
- Sterling Silver
92.5% silver, 7.5% copper, hallmarked 925
- Fine Silver
Pure silver with no copper content, does not tarnish. I use this for enamelling.
- Bi-metal
A thin layer of 18 or 22ct gold permanently bonded on to sterling silver.
- Titanium
A very hard metal which can be coloured by using an electric current or an open flame (I use a flame). This metal cannot be soldered and is not hallmarked.
- Brass and Copper
Base metals, not hallmarked.
- Stainless Steel
I use this for the pins of the brooches because it is far stronger than sterling
silver.
- Vitreous Enamel
High temperature, transparent enamel. I use transparent enamels because I love
the way the silver shines through the enamel.
