I placed the strips randomly tin or air side down. In the first they were shingled, and then fused. In the second, they were shaped first then fused. The first went into a self-made ceramic mould.

The second I decided to make into a large tray. The mould for this, as I had no suitable mould of the correct size, became cut kiln shelves arranged in a parallogram and covered with thinfire.

I fired at 100C per hour and watched periodically from 600C top 720C. I decided to stop the firing after 10 minutes at 720C. This was not an entirely successful experiment, as only a little devitrification shows on the first and none on the second tray. Still, I obtained two interesting vessels, which encourages me to continue the experimentation.
