Hi All my name is Rachel and I have got a problem with my very large
oval Olympic kiln I think its the largest kiln they make not sure if
this will be relevant or not just wanted you to get the size of the
possible problem which is.........
I make ceramic torso's life size and have always used a bronze glaze for
them, I also dabble in Egyptian paste containing Copper Carb and Soda
Ash the egyptian paste I have always fired in my test Kiln with out any
problems arising or any adverse effects of other glazed bodies.
I decided to make a torso in Egyptian paste and made 2 life size casts
and fired them in my Olympic electric Kiln all went well until I needed
to fire some bronze torso's some weeks later and the bronze glaze came
out near black with a glitter effect, shocked at the results I did fire
another 2 torso and got the same black results I did test the Bronze
glaze first in the test kiln and all was well
I presume now that the kiln is contaminated as the Egyptian paste was so
large not sure if it was the copper or the soda ash my question is how
do (if I can) counteract the damage or will it diminish with time or
maybe take the kiln to stoneware and hopefully burning off the damage or
is it new elements, if I replace the elements will the bricks/shelves
etc still be contaminated.
Happy New Year to everyone
