This week I spent a day at Warm Glass, near Bristol.
As their name implies if you need anything for fusing glass, these are the people to speak to.
I've bought lots of materials from them and attended a couple of their online courses, but they've just started to run in-person sessions again and when I saw they were doing one on dropouts I had to sign up.
When fusing glass you can get different effects depending on the temperature you set your kiln to. You can do a full fuse which will make everything melt down into a flat sheet. You can do a tack fuse so that things stick to each other but don't loose their shape. And you can slump your glass, by putting a sheet into a mould and heating it just enough that it slumps into the mould and takes its shape.
With dropouts your mould has a hole in which the glass can melt through, giving all sorts of effects and creating vases and bowls.
On the day we actually did the process backwards. We started with a dropout which had already been made, so we could practice cutting it and then coldworking the cut edge. You can do this by hand or with a machine, so it was great to have a go at a few different techniques.
The glass is also quite fragile. So while I started with a tall vase, while cold working it, cracks appeared and so it got shorter. I'm still very happy with it though.
Next we designed our slabs for dropping. They need to be a certain size to fit the mould and at least 12mm of glass in the middle. These were later fired for us and posted to use ready to try dropping in our own kilns.
While all this was happening the big kiln had been heating up in the other room. This already had 4 slabs set up and as the afternoon progressed we got to watch as the glass melted and dropped. This gave us a really good understanding of what we should be looking out for when dropping our own slabs.
We also had one of these posted out to use, so we could practice cutting and cold working at home.
I really enjoyed this course. It's one of those things that isn't quite as difficult as you fear it might be. And it was lovely to spend time with other like-minded people. I learnt lots from them too.
And I love the fact that you can used off cuts to make your slab. Another way to save waste in the studio. I'm looking forward to playing with this technique.
