Hi, thanks everyone.
In answer to your questions:
1. Firing to 1240
2. Oxidation in electric kiln
3. G72150 multi-purpose stoneware transparent glaze, firing range 1200 - 1290
4a. I first used Mason Peacock 6266 at 8% (with the china clay/ ball clay slip - oh, also with a little feldspar potash, recommended by the supplier)
This resulted in a very dark blue - could I rectify this by just diluting it with more of the ball/china/little bit of potash clay slip?
4b. Then I used Mason Deep Turquoise 6315 at 8% (with the more complicated slip)
I was advised to add the feldspar potash and the silica by the supplier that I bought the stains from, but it resulted in a very washed out anaemic blue instead of the deep turquoise.
I imagine I should just forget about the complicated slip?
Am I still ok using the ball clay/china clay/little bit of potash slip with the stoneware (I have mixed up quite a bit)?
Would there be any difference between using this and a slip made from the white stoneware clay?
I'm after a pure colour, as shown on the Mason stains chart.
I saw an old post of yours, searching for recommendations about Rhode or Nabertherm kiln. Which one did you purchase after all? And what is your experience with the chosen one?
I'm asking as I'm trying to decide myself. I have a 20 years old Rhode (working great to 1250 C) but need a new one (for cone 10).
