Glaze Firing Results

I unloaded my latest low temperature glaze firing this week. It was mostly successful. Some of my color application inside is a little thin and one bowl cracked.

I decided to slip trail the same design on the cups and paint the interiors with a baby blue underglaze. I didn't get the coverage I should have gotten with the blue--probably because I was rushing, but I'm generally happy with the design.

 I used the same slip trailing on some of the bowls and plates.

The color is a bit irregular because these are the same plates I tried to use bubbles on earlier in the summer. The bubbles don't show up with the clear glaze on top, but some of the iron oxide drips show through the clear, making the newly fired pieces look dirty in some spots.

On one bubble bowl, I traced the original bubble design with my slip trailer. I actually like the design and should have done more of it. Maybe I will revisit the idea in future glaze firings.

When my daughter joined me on Sunday, I filled a larger slip trailer for her. She used it some, but there was underglaze leftover in the bottle when she finished, so I started using it. I used red underglaze in the large bottle, purple in the medium size and black in the small like the other bowls.

A few of the pieces had some level of glaze on them already. One bowl had patchy pink underglaze on it already and I added blue over the top. It must have had a bit of glaze on it already, too, because the new underglaze took forever to dry. The retire is still fairly patchy.

One of the bubble pieces had green underglaze applied before the iron oxide bubbles, so it was green before I slip trailed. I like the design alright, but its certainly an odd piece in this batch.

I had fun with the slip trailing and I came up with some patterns or design motifs I'd like to use in the next glaze batch I try.

I like the circle pattern on the rim, but with a brighter color for the large circles

I think I'll mainly use slip trailing and subtle interior glazes again on the next pieces. The glazes are different, however, so I may need to run one batch through the kiln to get used to them.

I like that these lines are not straight

I expect to take some of this work to Oak Hollow this coming weekend for the holiday show. I'll find out then what Josey wants to keep for the show. I don't anticipate the next batch of work getting glazed until December, at the earliest.

the lines on the right also wiggle a bit

My daughter also glazed some work. She prefers the slip trailer for dripping underglaze and she also liked using the round foam stamps for the red and purple. her blue underglaze application, ironically, is more even than mine.
