This one I decided to test a porcelain slip on. I plan on carving a design in the white slip area that will allow the red clay to peek through.

These crosses have become such a staple in my studio that I can pratically do them with my eyes closed. It is so much quicker making 10 of one thing than one thing 10 different times.
I needed to throw something today. My drying shelves are completely bare and that just can't be. According to my schedule I need to throw mugs. It's been about a month since I threw some mugs so I decided to throw some stoneware mugs first to get in the swing of things before using my red clay.
After throwing the 3rd flop, I decided the clay was too plastic and would never give me a good mug. This is recycled clay. What I'll have to do is wedge it with some new stoneware and try again. I gathered all of the clay and covered it in plastic. I'll wedge it tomorrow.
I stained 10 crosses with black iron oxide which finished these up. Messy job. Have to wear gloves.
Decided the letters on these hearts needed to be filled in with stain to make the letters pop. We'll see how they turn out. These are the first to get finished. They'll go to Sara to be designed into keychains. If they look good and work good (not sure the holes are big enough), then I can put them through to be finished for the Brownie Troop coming in April.
And loaded the kiln. Included in this load are 4 ice cream bowls, 1 herb planter, the mini vases I glazed yesterday, 10 crosses and about that many hearts. I also threw in some test porcelain beads for Sara to design with.
It felt good to get in the studio and start working again. Empty shelves greeted me as I strolled in at 5 am with a warm cup of tea in my hand. Hopefully by the end of the week these shelves will be full of glazed pieces ready for the kiln.
I could only work for 2 hours today so I decided to finish up some small projects. There were 2 small pieces that I wanted to wax and a mini vase that I needed to finish glazing.
I also went over my production list to see what I needed to concentrate on for the week. It looks like I need to throw some more mugs in both stoneware and red clay and roll out some more crosses and heart key chains.
Bailey Pottery has the best price at $702 for the unit, $95 per each 1 gallon jar (need 2), and $9.79 per lb of pebbles (need 16lbs). Total $1048. plus shipping.

Up to this point, inefficient methods of processing my clay have been reasons I was tempted to purchase outside clay for my studio. What I would like to do now is analyze the aesthetic reasons why I'm tempted and then figure out how I can overcome them.
The first one is color. My hand-dug clay is RED. Oklahoma Red to be exact. Red clay means lots and lots of iron. Lots of iron in clay overpowers whatever color glaze you apply to your pots. Most colors applied to my red clay come out brown. So far I have found only 2 glazes that look good on my red clay; midnight blue and a satiny, metallic brown. To get pretty colors you need a light colored clay. The clay I purchase is a nice light tan, color works well on it and I can get whatever look I want. What potter doesn’t like to play with pretty colors?
In my research I have come up with a few things I could do to remedy the color issue with my red clay.
- Send samples of my clay to a laboratory to have it analyzed. This will allow me to experiment with making my own glazes using a glaze software program that I got for Christmas. I need to know exactly what my clay is made out of in order to make a glaze that will fit well and maybe have color. To have my clay analyzed it will cost me approx. $100.
- Run my clay under a magnetic field to remove some of the iron. I have wanted to try this to see if this is possible. The one thing I don’t want to do though is change the color of my clay. The fact that my red clay is Oklahoma Red is a huge selling point in this neck of the woods.
- Use a Majolica glaze. Majolica is an opaque white glaze that covers dark clay. You can then paint your design in colors onto the white glaze background. Typical Majolica pottery looks like this.
All of these methods of coloring my clay is feasible and would be fun. I especially like the slip method and have already tested it on a few pots. To be good at any one method though will take time and will require patience on my part. I also really want to get my clay analyzed. I think this would speed up my testing and give me the security of knowing my product.
