@vik@mastodon.nzoss.nz .. repeat settle/skim/pour until consistent, dry in sun, grind with a rock, add water to preference, coil, shape by hand, cut down tree, dry pot and wood, texture pot with twigs, fill hole in lawn with wood and pot, dig air trench to hole, light fire, waft air into trench, get very very hot (850C ish best estimate, not vitrification but sturdy vase), bury hot coals, cool, dig up and profit. Overall I lost maybe one third to firing shatter. The key thing is long drying and preheat

@samworm@toot.community Anything over 700C should fire it good enough so 850C is definitely ample. Aluminum melts at 660C so if it's not hot enough to melt a bit of aluminum scrap it's not going to fire a pot.
