I have a love / hate relationship with my glaze. When it’s good it’s fine and when it’s bad it’s beautiful. Let me explain, at my normal temperature (you probably already know this from my past problems with the kiln etc) it’s fine, it melts well, makes a good colour (until recently when it’s been getting a bit less honey and a bit more yellow which I don’t like and am not sure how that happened) and is pretty durable for an earthenware glaze. Any lower and it’s dull, no gleam and just looks a bit sickly. Just that bit higher and it’s delicious, so warm and deep and lovely it makes me drool. However at the just higher than normal temperature it also shimmers. Humph!
I would love to get it so that I can take it just that bit higher, the black slip almost melts under the glaze and it’s lovely. So what do I do? I have been trying to get my head round this for ages. Obviously I don’t want to alter the recipe too much. These bowls in the picture above are glazed in a slight tweak to my normal glaze, more clay less lead. I was hoping that would put the colour back to how it was but it has if anything gone a bit darker and it doesn’t sing to me as I would like it too.
