Full fuse firing schedule to keep my bubbles?

Postby claire9596 » Wed Sep 15, 2010 11:59 am

Hi Mary Kay,
I have a new paragon GL24 and am in the process of firing 2 projects to include bubbles. I have 2mm stringers crisscrossing between two 3mm bases. I have done this on a smaller scale in my smaller kiln with good results.
But I am uncertain as to the full fuse schedule for my new kiln to keep the bubbles.
Can you give me an idea of a full fuse firing schedule to keep my bubbles?
The bullseye tip sheet did not give that information.
Thank you

Hi Claire,

Mary Kay is out of the office for a few days. A full fuse will trap bubbles within the stringer grid. The basic fuse firing on page 4 of Tipsheet 7: Platemaking should work http://www.bullseyeglass.com/pdf/technotes_tipsheets/TipSheet_07.pdf.

Good luck.

Thanks Jim. But with the platemaking firing schedule, isn't the 600 to 1480 to help sqeeze bubbles out?
What would happen to the glass if I went AFAP during that stage?

Hi Claire,

The bubble soak is achieved by holding for 30+ minutes at 1250F. I don’t think much would change if you went AFAP from the bubble soak hold to 1480F, although you may have to soak a little longer at 1480F to achieve your desired results. The bubble soak should not remove the intentional bubble pattern you are trying to create.
