Title: Slumping in a Bead Cube - HELP!
Post by: Kathy on January 04, 2013, 08:32:11 AM
Hi there

I have some miniture bottles and I'm sure I remember reading that the bead cube can be used for slumping - is this right? I have searched and searched but am not really sure what I am looking for or how to do it at all really!

Any help would be gratefully received :-[

Thanks, Kathy x

I'm glad you asked that question Kathy cos DH wants to have a go at slumping/fusing, so hopefully someone will have an easy answer!

I found this info:

Effetre Moretti Glass has a C.O.E. 104.
Annealing Temperature 480-500c.
Fusing Temperature approx 720c.
Slumping Temperature approx 620c

and this in the bead cube info:

This will allow the kiln to be used for trying other mediums such as fusing or PMC right through to its maximum temperature of 920c although the kiln is primarily a bead annealer.

Hope it helps, Janet

Kathy, have a look at this site - gives lots of info on various firing schedules:
http://www.glasscampus.com/tutorials.htm

Another datasheet I have found very useful is this one:
http://www.warm-glass.co.uk/images/pdfs/products/Basic%20Firing%20Schedules%20for%20most%20kilns.pdf

If my memory hasn't totally left the building I seem to remember that bottle glass has a COE between 80 and 85. If you start by following temperature schedules as for Bullseye glass you shouldn't be too far off.

Good luck!  :)
