Deep joy opening the kiln…….but……

It was deep joy indeed when I opened the kiln on Friday, however I soon realised I need to keep better notes. I must remember to write stuff down.

It’s been weeks since I glazed these vases, it was the second time for glazing as the first time round the colours didn’t run and merge together. These are Botz stoneware glazes which I layered up and also gave them a coat of a Botz product called Brilliant Effect, this makes the glazes run and gives some lovely effects.

I realised I’d not applied it thick enough the first time these pots were fired so I reapplied glazes and BF and fired again. Result!


P1450652I love making these little pouring bowls and I love the way this one has turned out, it has some pinholes so I may decide to fire it again. I love the effect on this pot but here lies the problem.

P1450653I forgot to write down the glaze combinations for each pot, I know there’s turquoise granite on this little pourer, and I know the glaze combinations are based on the tests I did for my dinner set but which is which?

Here’s the test tiles again to compare.

botzI think I can safely say this little thistle vase is number 3. Creme and Ice Crystal, the only reason I remember is because my daughter liked this one best.


I really don’t know what this one is.P1450665

I suspect this is number 1. which was my favourite, Creme, Turquoise Granite and Blue Black Speckle. It’s a gorgeous vibrant blue, with white green and turquoise runs.P1450669

So in future I need to write things down, the memory is not what it used to be .

I think I have made my mind up finally for the dinner set , I’m going to glaze with Blue Black Speckle ( as I thought I would ), it’s giving consistent results, I like the colour and the satin look. Here’s another serving bowl which came out the kiln on Friday, I do like the way the BBS glaze has broken on my ribbed dish. Also if I keep adding to my set if I use a glaze straight out of the pot I should get consistent results each time, so Blue Black Speckle is a winner!


I’m just about up to date with my work so hopefully the dinner set glazing should commence next week 🙂

Botz Glaze Mixing Experiments

In preparation for glazing my dinner set I’ve done some experiments combining Botz stoneware glazes. Having spent so long making this set the last thing I want to do is to mess up when it comes to the glazing. I find glazing has it’s own problems but I won’t go there today.

Botz stoneware glazes were chosen because they are lead free and non toxic.

The samples are numbered, and I managed to write down which glazes went where, something I regularly forget to do as I’m so wrapped up in the process.

I applied two coats of each glaze, layering and overlapping them. The back side had 2 layers of Botz Plus as well as the same glazes as on the front. Trying to squeeze out as many glaze possibilities as I could the larger sample had 2 different glaze combinations.botz

Here’s a list of the glazes that I used.

  1. Creme – Turquoise granite – Black blue speckle.
  2. Creme – Turquoise granite – Bright blue effect.
  3. Creme – Ice crystal.
  4. Turquoise granite – Bright blue effect – White.
  5.  Ice crystal – Black blue speckle
  6. Black blue speckle –  (left side) – Ice crystal. (right side) – Bright blue.

I think I like the first combo best for the dinner set but I’m not entirely sure, I’m still considering the black blue speckle glaze  on it’s own that I used on the noodle bowl. I don’t mind eating off dark crockery but I know from research most people prefer light cream or white plates for food. But this set is for me, decisions, decisions 🙂

I love the running effects with the Botz Plus, but on plates I can’t imagine that the glazes will run as much. I have some spare plates made from another clay so maybe I should try  the glazes on those first. I feel I have blank paper syndrome, or in this case blank ceramic syndrome, and I need to get over it soon.

Also I need to do 3 coats of Creme instead of 2 for better coverage. I find it’s quite tricky getting even coverage with brush on glazes.

I haved to experiment further with hotter firing and a longer hold, but that’s for another experiment.

I want to get this set finished but I still feel a bit wary about glazing it.
Which glaze combo do you like best?
