I ran a glaze firing in my electric kiln last week. I’d say I got mixed results, but ended up with some nice pieces and lots of information. The new functional ware is up in the shop here. This bowl mug is by far my favorite this time 🙂
I would say I got mixed results because I’m dealing with some common potter problems. When you run a glaze firing there are a number of things that can go wrong. Two of the most common glaze defects are pinholes and blisters. I have been seeing both on my work and it’s super frustrating. I put in a lot of time and effort creating my pieces and carefully glazing them. When I open up a freshly fired kiln only to see glaze defects it’s disheartening.
For example, I created two pitchers for this last firing.
They both ended up having gorgeous glaze combinations, but they have too many defects for me to feel comfortable selling them due to major blistering on the inside and out.
On the one hand, cool I get a couple of pretty pitchers to use personally. On the other hand, I want to smash them in my frustration! Unfortunately it was more than just these two pitchers that came out of the kiln blistered. Fortunately, a lot of the other work is usable in one way or another. I don’t like to sell work with lots of glaze defects if it’s going to be used for food or drink. It isn’t a big deal if the work is more decorative though, like vases and the candles I am working on.
So, after the initial disappointment of things not turning out the way I had hoped I went into research mode. I don’t need to go into all the details here. Glaze firing is more complected than one might think, even in an electric kiln. Suffice it to say, I now have a plan for the next glaze firing that I think will reduce/eliminate the pinholes and blisters. I will probably always be learning more in this craft, but ultimately the mistakes only push me to improve.
Looking forward I have plans for another pit firing in a week or so. I think the candles that are in the works will be pretty neat. I’m also thinking of making more mugs, bowls, cups, vases, pitchers and the like. I’m just going to keep moving forward!
