Recent Kiln Firing

I've been hoarding photos of the pottery from a recent kiln firing! I had the opportunity to fire a kiln with Anne Pärtna from Blue Hen Pottery at Dwight Holland's house. Not only was it a fun chance to help fire a gas salt kiln again, but it was a wonderful opportunity to get to meet and talk with Dwight Holland. Anne (graciously) loaded the kiln on the Friday before last:

The firing was on Sunday, I arrived in the afternoon to keep company while kiln-sitting, and to help salt.

I also had the pleasure of meeting Thor, Dwight's great dane. Thor's playtoys were five-gallon buckets!

We salted around dusk, which brought back memories of chucking burritos of salt and dumping angle irons of salt into the gas kiln at Berea. The salt port on this kiln, however, was on top, which I liked very much. Most of the older kilns I saw while in Germany were salted from the top, which I think it is a very good design for getting a good coating on everything.

The kiln was opened up last Wednesday and the results were good.

I didn't have that many pieces in the kiln, just some tests of forms and clay bodies. The rope handle pitchers and small jars I made a while ago turned out well. I am glad that I recently made larger teapots though because the final teapots I made previously are much smaller than what I think should go with a tea set (something I'm working on). And the ring vases turned out well too, so I definitely think I will make some more soon. Here are some photos of the results:
Two mugs. The glass melted very nicely and flowed through the faceting splendidly.

The glass also blushed with some reds, which was new to me! Whether it was off-gasing from a glaze, or just the atmostphere of a gas fired kiln, I don't know! Ah, the wonders of making pottery!

Small lidded jar. This lid turned out pretty well. Some of the lids ended up standing above the rim, which only means I need to work on lids more!

The twists stayed in tact and picked up the salt nicely. Feels good too.

Brenda, I'm guessing that copper makes your glass green and when copper is reduced it turns......red! Nice looking pots!

Super looking pots! So you embed glass in the clay surface? What temp. are you taking it up to? What kind of glass? (Sorry I'm so nosey... just haven't seen this before) Email me if you get a chance.

Hi Dan, I thought of copper too, but where that copper was in the kiln I have not figured out! None of my glazes have it, and I don't think the person I fired with had it! Or are you implying in the clay body? TropiClay, check out my post on bottle glass (http://libertystoneware.blogspot.com/2010/10/green-bottle-glass.html) where I go into a little more detail on the green wine bottle glass that I break up and embed it in green ware before bisquing. If you have any more questions, do ask! Or feel free to e-mail me at libertystoneware@gmail.com

Hei Girl, good to see this post! Sorry I'm just now checking in... As for copper - the blueish green glaze that I use to line, has Copper Carb, so it could have blushed from that. And we had nice reduction, so quite possibly the copper in the glass blushed...
Anyways. It was great firing with you and I'm so glad you met Dwight. Looks like you two could talk for hours:)!
Hope to see you soon!
