Fine Silver Wire
Fine silver wire can withstand the heat of a kiln while the glass melts around it. It can be looped and buried in the glass during firing to make a bail for attaching to other pieces such as a necklace, etc.
Fine silver doesn't just come in wire form. Try utilizing other forms of silver such as; fine silver foil, shavings, powder or leaf. They can all be used as an inclusion in glass. Make sure you allow a bubble squeeze or add some frit on the edges to avoid bubbles during the firing process.
Fine silver or pure silver is .999 pure while sterling silver is only .925 pure. Sterling silver is made up of silver and copper and/or other metals therefore it doesn’t work well in glass fusing.
If using the wire to make a bail, keep in mind that firing the silver in a kiln makes it very soft. Once the wire has been fired inside a kiln, it will have a white matt look. This white matt will need to be cleaned off of the piece after firing, and the metal will need to be hardened. It is recommended that the fused piece is tumbled in a tumbler with some stainless steel shot for about a half an hour to make is shine and harden up the metal.
Silver can be very reactive when heated. This might result in changes you were not anticipating in your piece. It can cause some chemical reactions inside the kiln. The reactions might stain the kiln shelf, change shades of glass, etc. Fine silver is very sensitive to the influence of copper inside the kiln. It is highly recommended that a lot of testing be done, or that the wire be coated before firing.
