Can anyone provide information or images to share on ideal uses and firing schedules for the Rod Pod mold. Flame and kiln workers alike are very intrigued in New Zealand!

Hi Claudia, and greetings to New Zealand kilnformers!

Bonnie located some notes about using the Rod Pods, which she shared with me:

Kilnformed rods may be used as small-scale pattern or simple murrine elements in kilnformed works, flameworked to make beads, or flameworked to make elements for kilnforming.

Rod Pod Mold user notes:

Before firing, prepare with kilnwash and kiln dry as directed. (500°F for :20)

Stay within the footprint of the mold and fill the channels with BE compatible material (sheet, rod, stringer, or frit).

To fuse rods for flameworking, firing cooler than a full fuse is often hot enough to bring the material together and minimize stuck primer (as this can get scummy in the flame). Clean well before flameworking.

To prepare for the next firing, remove used primer from the mold with a green scrub pad, apply fresh primer and kiln-dry.

In the torch, minimize thermal shock by warming the end of the kilnformed rod with the propane-only flame, let carbon build up, then add oxygen and adjust to a neutral flame – now working out at the tip of the flame. Once the carbon burns off and the glass begins to soften, bring it into the hotter part of the flame for making beads or flameworked components for kilnforming. Layered kilnformed rods can be great stock for making small scale twisted cane or variegated beads.

Rate(°F/hr) Temp(°F) Hold
400 1250 :30

600 1460 :10

9999 900 1:00

100 700 :01

9999 70 :01

Kilnformed rods of this scale can generally be cut with rod nippers (or certainly a tile saw) and used in kilnforming applications. One option: Chop or slice around 8-10 mm thick, lay-up on end, dam the perimeter and refire.

I hope you find this helpful!
