Bowls awaiting selection.
The line to get into the 'bowl room' just before 11 am. (that's my display on the left, still up from the Treasures of the Earth show)
I finished up things today. These 5 pounders got handles and will get slipped tomorrow. I made six but only 4 made the cut. Tomorrow I am working all day on tearing out the existing stairway and installing a new stairwell and stairs. It's probably going to be a long day. The new stairwell will have a door at the bottom, the new stairs have to be steeper to accomodate this change. I am going to miss the old stairs, I've climbed them many times over the past 10 years. Anyhow, change is good, at least that's what I've heard.
I baked this cake last night for our Valentine's Day dessert. Sarah had a late appointment with a client so I cooked dinner, Pad Thai, Sarah's favorite. It's also quick and easy. This 'cake' was pretty easy too. It has no flour but it does have 1 lb of bittersweet chocolate, and 9 eggs. Not so good for you but it sure tasted great...with a little whipped creme on top.
So I hope to get a couple boards of mugs made tomorrow and then on Friday I'll have bisque. As soon as this other stuff dries I'll do another bisque (hopefully next week) and then I'll be firing the salt kiln.
I worked a half day today and got a lot done. I slipped all the spoon jars and deep bowls from yesterday. I also got feet cut on a couple 6 lb bowls and all the feet cut on my soup/cereal bowls. These all then got handled and slipped. I didn't get my plates footed, I'll do that tomorrow, they weren't quite ready and I tend to mess them up if I try and rush it.
This morning I have to get my truck loaded up and go into town to the Cleveland County Arts Council to set up for the Treasures of the Earth pottery show. This is the 10th or 11th year for this show and I have done it since the beginning. It's a month long exhibit featuring about 20 potters from the region. The work ranges from hobby potters to serious amateurs to professional potters. I got everything boxed up yesterday and my display all dusted off. It's a good show and the reception always brings out lots of pottery enthusiasts.

As to my slip problem, I am still thinking about the cause. I have conflicting information regarding body reduction. I do know I over reduced this kiln for most of the firing. I need a neutral atmosphere to get my colors to be bright. Probably with an oxidizing soak for at least one hour at the end. I would like to start salting a little earlier so that I could finish around cone 9 also. I think this will help with the color. I think my slip problem is something that is happening early in the firing, before cone 08. ? Maybe things are getting too hot too fast, or I am trapping carbon gas under the slip. I may need to improve on my bisque to be sure I am burning out all the organics. Or soak for an hour at 1650 to be sure during my glaze firing. The problem is only with the high alumnia slip. Lots of info and variables to think about.
Here is an example of what went wrong. I have emailed several people for help today and gotten some good response. Phil Rogers says he had this problem for a while and believes it is a firing problem. He suggests a hard body reduction at cone 09 followed by a short oxidation then back into light reduction for the remainder of the firing. He believes the residual salt is sealing the surface when the pots get hot early in the firing and the reduction cannot get to it. He also mentioned I may be able to save these pots by refiring them to cone 9, 10 in a neutral or oxidizing atmosphere.
I'll be getting the pots brought in tomorrow. I'll get some pictures of some of the successful ones up then. Sarah took a look at the pots today and was more optimistic than I was. (She always is). She said it wasn't nearly as bad as my previous firing. Ha! She's right. I can be a person who sees the glass half full too....half full of poison. (stolen from Woody Allen).
