Crawling Green Glaze

I've decided I will feature interesting things about the ceramics stuff I post since I am now churning out a lot and it isn't so interesting to see picture after picture of bowls.

Today's feature is this crawling green glaze on one of my cups that recently came out of the kiln.

From what I can tell, glazes crawl when you put a lot of them on and they have the characteristic of crawling. It means something is melting in the glaze and dripping down the side as the kiln heats up.

Because this glaze crawls and creates these cool bubbles, this cup can't be used for food or drink (it will be hard to clean it effectively). The picture above is what the inside of the cup looks like, you can see the glaze is pooling.

I kind of love this crawling and bubbling the glaze is doing. Right now I have a flower pot in the kiln that has this glaze near the top. Hopefully it will compliment the green under-glaze I've layered on below it. The trick is learning to predict its movements.

I haven't developed any of my own glazes this semester. I feel I don't have time to really make and test glazes, so I'm just using the ones they provide in the studio. Maybe if I start renting a studio and have more time I can make test pieces and send them through with some of my own glazes...
