It reminded me just how much I love everything about glass. The light coming through it, the colours, the feel of a large piece in my hand, the act of cutting it and listening for the sound all the time. Lifting the cutter out of holes where there are faults in the glass. The careful snap, or easing a cut, or occasionally tapping the back of a sharp curve to control the line of cracking. Glass may be man-made, yet it shares many properties with crystals and gemstones – and each colour seems to have its own cutting character influenced by the specific minerals which make the colour. Red, made with gold, tin or selenium, is always really nice to work with! The opposite of green, made from iron or chromium, which can be one of the flakiest and always the most likely to give me nicks. Amber is harder, iron plus sulphur, good bottle glass.
Copper foiling isn’t my preferred technique, but appropriate here so I dutifully wrapped each piece in the required sticky copper tape before the joy of soldering. The acid tang and spicy smell of the flux, so different from the tallow I use on lead. And the way molten solder behaves is just so fascinating. Sometimes it melts cleanly, other times it feels more solid depending on the exact temperatures. Most of the time it flows beautifully into a joint, making a raised silver bead, but occasionally it reminds me of my lack of practice recently when it hisses and spits gently where there is an air pocket, or even runs straight through when it gets too hot. And when it runs out it makes a beautiful silver puddle, ready to be gathered up again with the iron tip and reused. And the final stage is so simple – a bath in warm soapy water. No mess.
