I made a murrini in the torch using bullseye rod 0024-tomato red opal, 0321-pumpkin orange opal, and ???-deep cobalt, it is about 200mm long,33 mm wide, and 33mm high. As it was placed in the kiln it broke into 9 pieces, the largest is about 76mm long 33mmx33mm. I have puzzled the pieces together with minimal gaps. My plan is to add a 200mm, 36mm wide, 3mm tall strips of 0024-tomato red opal on each of the 4 sides, damn (using thinfire paper since it is all I have) and bring to a full fuse. The murrini is not perfectly straight so I plan to fill any gaps with fine frit made from broken rod ends. Can you help me with an appropriate schedule to slowly BRING IT UP to full fuse and hopefully minimize any bubbles in the process? Once it is up to temp I assume I can use the thick slabs information sheet for annealing and cooling schedule.
I fuse in a abused (purchased used) very small (14'?)Jen ken kiln with ceiling elements and a thin shelf raised 1/2 in off the floor.
My original plan was to build a wider pattern bar using the murrini as the center but after the breaking I want to save what I have before attempting to add more elements.
Thanks so much for any advice you can provide,
