First disappointments
I
have just opened a kiln after a first glaze firing. It was a test for the kiln
as well as the glazes. Firing went ok and the kiln has reached the temperature
(1210oC) without any problems, but when I opened it, glaze didn’t
look the way I expected it to.
I don’t mind the crawl
surface, but it obscures all textures underneath.
Not what I wanted. I have spent so much time creating those textures, I don't want to lose them.
This is what I expected, as I used the same combination of glazes as on the Gateway arch:
This is what I expected, as I used the same combination of glazes as on the Gateway arch:
Why
is it happening? Is it due to the change of raw materials? (Very likely as I
witnessed problems with other high feldspar glazes) Did I make a mistake when mixing? (Not likely
as I bought just enough raw materials for two glazes, and had no unexplained
leftovers)
So
what else can I do? I can’t quite picture the sphere in any other glaze. First
reaction is to test whatever is immediately available in the studio: test glazes
separately, test clear glaze and very thin washed out application of dry green
glaze, just in the crevices. I also want to see what it looks like without the
glaze.
So I
used broken bits, applied glazes and put them back in the kiln. Restarted
it......and instead of a click that announces heating has begun, there are
sparks and silence. Controller looks dead.
Silence.
Disbelief.
Studio
still has working lights. Press a few buttons on a
controller – no response. Fuse has short circuited. And that is the limit of what I can do. Except call
kiln electrician.
What
was that I said about patience?
I love the glaze texture, the result of that on top of the one you created in the clay makes it very complex and rich. Show us an example of the glaze surface you intended to achieve please?
ReplyDeleteAh, I forgot to mention....intended glaze is what I used on the arch ( Gateway 21). will post picture soon
DeleteYes, I like it too .....but yes, pity about losing your textures underneath .... glazing (for me) is always a case of 'expect the unexpected'.
ReplyDeleteThat is very true.....especially now that some materials are sourced from different places.
