Hi everyone from Sunny Ireland!
Im hoping someone can help before I ruin another load of work!
Pot on the left is what I am trying to achieve, it was a happy accident as I just wanted to fill a space. I think I put a thinish layer of Copper Carbonate on then a layer of transparent glaze and fired to cone 05. Delighted with the colour I tried to repeat it,
Pot in the middle has a thick layer of the same , my thinking was it would be even more blue, it wasnt!!
The next item was treated the same and the transparent glaze seems to have crazed and cracked and is a nasty colour , the final item had no transparent glaze on it , again black/brown colour.
How can they be so different? Was it because I put a thick layer on and why would the transparent glaze react that way?
I know there will be someone in this community who can help, Thanks So much, Jools
What did I do?

Thanks Callie for explaining all that in such detail/ It was my hunch that it was too thick but so glad you have confirmed that and I can get back to work. Have a great day, Jools
