i got to work with greg daly this week, doing lustre firing. he heats the kiln up and then does cycles of reduction and oxidation, pulling test rings as he goes. the unburnt gas gets combusted (by lighter) as it leaves the kiln, resulting in a pretty bananas rush of flame above the kiln. felt like a bit of a bad ass when i got to do my own cycling. now i just need to develope a base glaze, a pigment suspension, the correct amount of silver, etc, and do about a thousand tests and i can legit lustre fire.
