Dear Andy and Dale
So nice to spent time together.
the firing , yes .
I only fire electric and i normally do not fire bisquit.
The glazing of the "green"pots is a craft itself i've learned through
the years , glazes react pretty different on "green"clay.
The kiln is loaded the day before , in the morning
power goes on at , he starts pendeling = go off and on for all houres.
i fire from start to 1240 "C normally in 12/13 houres.
I also never go above 100"C per hour.
My kiln pendels semi automatic.
I start with 10% on -20% off ... at the quartspoints ... at the temps
the upgoing falls back , i manually change the duration of the pendel.
After 12 hours it is 25 % on - 10% off.
The first 150 degrees i leave the opening in the kiln a bit wide.
After that it goes almost closed , but enough room to see
the glow and atmosfere inside the kiln.
I also look very often at the color of the glow .
its like a clock and must say i can read it pretty close.
As the 1240 is there , i hold this temp manually
for half an hour and shut everything off .
Close the lookinghole , and let it cool down .
It is a matter of patience but i've learned the glazes
are better as i let it cool for 24 houres.
During firing , i am every hour at my kiln .
It is wonderful to see the glow in the night .
Later more
Kind regards
Morea
