Time to turn it up another notch! 5:15. just turned it up to the third notch(no color yet iniside- can still see the light from the flames. Interestingly I had to adjust the oxygen flow on three of the burners. They were giving an orange flame(indictive of a reduction) to give me a uniformed blue-oxidation flame. So the thing is begining to hum. Imagine your furnace at hiome when the flame kicks on. now multiply that about 20 times(I have 14 burners each rated to 60K BTU/hour.) Gas flow axes out at about 5.2" output. I will let it soak here until I get an orange glow inside. Then turn it up, close the flue so the opening is only about 1/3(flue dimentions are about 18" x 12".) In full reduction, flue is almost completely cvlosed. That's where the magical reduction process begins in earnest. Flames are running through the kiln looking for oxygen it can rob from any where. SO it takes from the materials in the glaze, chiefly the copper carb(to change green to red) as well as the rutile to give the celadons their mystical allure. Think I'll go to 7/11 and get a gallon og coffee<GG> Soak period at this level could be up to two hours.
