Reduction

Cone 9 is nearly down at the top of the kiln,cone 8 nearly down on the bottom,so a chance to blast away with some heavy reduction for the last half-hour or so- the chimney slot on the Laser is closed to within a couple of centimetres,and the gas pressure turned up,resulting in lots of noise and flame from various orifices,with the temperature dropping because the gas can't get enough oxygen in the kiln to burn properly [that's why the gas escaping from the kiln burns- as soon as it leaves the kiln it finds the oxygen it was looking for].I probably have another 10 degrees to play with [I just eased off the chimney damper,the kiln is starting to climb again,slowly] before 9 is totally down on top: time for lots of reduction for the anagama refires I'm doing,inspired by the success of refires from Ricardo's kiln in the last firing.
