Annealing Silver Glass

[helenfc]

Hello I have been batch annealing my beads at a high of 520c. I have some silver glass beads im v happy with (but dont want to speak too soon...) in the blanket. I have seen a few threads on here from people saying they anneal their silver glass at a lower temp than this...so would anyone care to share their silver glass batch annealing schedule with me?
please please pretty please

To be fair, I think it depends on the kiln - most are fine.

I tend to anneal at 520°C (sometimes 545°C) without issues. Some folk need to put carbon (or something in their kiln, I'm not 100% sure).

For a while back I tried annealing lower and longer but it made no difference to me - but here is some info http://www.frit-happens.co.uk/wiki/Annealing (this is for an as you go - you jsut need to change the details from ramp 2 I think)

And I have had reports that some silver glass doesn't like to be garaged too long - so if you find a particular colour an issue you could try saving it till the end of your session! (again this is for as you go - but worth knowing!)

Terra used to be a fussy one, not sure about the new one. Strikers are the problem, they can over cook. If you want to lower the temp you can balance it by increasing the soak time, depending on the size of your beads.

I batch anneal too, but at a lower temp. To be fair, the high temperature isn't so much of the issue, it's making sure you ramp down slowly enough through the stress point of the glass.
So anyway, I anneal at 489c and always have a pea sized amount or carbon in the kiln for silver glass. The carbon you buy for fish tanks from the pet shop is easy to get hold of and does the job
