Well, the holiday is over – not that it ever started. The kiln has been going non stop – lots of new silver and even more glass pieces – the first ones were just a test – to test the new glass moulds, well, they are great, if you stick to the instructions everyting comes out just fine (at least with my kiln) even with one of the moulds a little damaged, it still works just fine.
The instructions I use for firing COE90 glass bits are:
Heat up very slowly to about 680°C. This temperature should be held for about 10 minutes. – Venting.
Then it’s a full fire to about 780°C. This should also be held for about 10 minutes, maybe even more depending on what you are doing. – Venting.
This is were you have to stop venting. – Your going into cool down. Do a full stop until you get to about 520°C. It should stay at this temperature for about 1 hour.
Now let the pieces cool to room temperature without opening the kiln.
The instructions should work for an average size pendant. – Of course it will depend on the glass you use and the type of kiln and how big the piece is.
Filling the moulds with a litle more or a little less worked fine for me, you just have to make sure you don’t make things too small.
I have included some examples of the first pieces that made it. I must get some more colours. I think I will make some more drops and turn them into earrings with the help of some silver bezels, and the black one wants to be a ring – he said so :-)
I have also been working on my webshop www.glasstwig.com – managed to get a slider working and I am retaking most of the pictures – so – lots to do – must get back to it…..
