This is how I spend much of my non-canine time, playing with fire...safely of course!
A glass bead starts out looking something like this! I have an ever growing collection of these rods.
Then I do some of this!
And some more fire! This can take awhile!
Eventually, the bead goes in this ugly, but effective kiln. The annealing cycle takes about 12 hours.
When all that is over, pretty beads come out of the kiln!
