Great and exciting.
A wonderful team
Beautiful! Fabulous! The old BBC series, Time Team, had a few episodes with side stories about early glass blowing. Those stories were fascinating; but too brief. This video is such a treat. Thank you!!! Love the forms and the background information.
What is your crucible recipi ?
My experience is that while bark is maybe 10% of the mass of the wood, it creates about 80% of the ash. If you want to reduce ash, remove the bark.
That's hot enough that it probably ashes based on mass (plenty of heat and air, like a 'masonry heater'), all that ash was white. When you see the black ash, that usually indicates a lack of oxygen or too much moisture in the wood causing an incomplete combustion. Bark is like a sponge to moisture, and modern stoves restrict airflow (in bid to improve efficiency) and many people don't season their wood properly, because seasoned wood burns fast. Thus, to the average wood burner, it seems bark makes way more ash than it should.
