Thanks for that, Robert.  I enjoyed the video, especially the discharge from the little "smokestack" tube atop the kiln.  The guy seemed like a happy potter.

They still use Globars in industry. I’ve always thought I’d like one. Those amazing modern oil spot kilns with metallic or blue spots are done in Globars where they reduce, often using small sticks of wood, all the way down.

There are some cool videos on YouTube, such as this one.
