Potters & Sculptors - Making Rock from Mud
Why Single Fire?
The more of those questions to which you answered "Yes", the more reasons for you to look into single firing.George Lewter from cone6pots.ning.com has started a single fire interest group. If we can get a committed group together to study the single fire process somewhat systematically, we will likely progress much faster than if we work individually in isolation. With a dedicated group we would also have a better chance of enlisting the aid of one or more established experts.
Here are some links to photographs of single fired pottery.
If you are ready to dive in then you'll need some techniques. You won't be able to use those glazing tongs on leather hard clay or on greenware.

Thanks for sharing. Marek and Pauline. I am going to try these. The cost of firing these days is so expensive and of course people don't want to pay the price that we deserve so we need to work out every way we can to reduce our time and cost of firing.
Firing bisque to a hotter cone like Cone 03, rather than a Cone 04 or 05, will eliminate excess porosity which causes these problems.
At our studio, excessively porous bisque tends to give people the perception that they've applied far less glaze than they have. As the clay body densifies at Cone 6, the result is a piece with a large excess of glaze and runs as the glaze is essentially wrung from the immature and excessively porous bisque.
Hey these are pretty nice! Are those stained glass inserts in clay shades?
Hi everyone. I Single fired a kiln load of Xmas Dec's using the same clay for entire kiln load of pieces (small kiln). Fired an earthenware clay to 1100c (no soak at 1100c) using a commercial clear over u/glaze dec. I just started using a new 'snow white e/w clay'. I have never had this issue ever before. The bottom shelf of dec's all shivered and glaze flaking off all pieces. Rest of kiln was okay. Any comments about this would be appreciated. I understand about shivering but not why only happened on the bottom shelf. Bottom shelf of my kiln fires a little cooler than the rest and cools quicker. Perhaps a temp variation? What do you think?

You can find the above recipes on the Lakeside Pottery glaze page, and elsewhere on the Internet. Just Google the glaze names. Some will say Cone 10 or reduction, but most of them will work at cone 6 oxidation when you layer them on top of each other and some work just fine by themselves at cone 6.
Low cost flat lapping disc can be used on you potters wheel if you, drill bat pin holes in it, and provide a trickle of water to cool it. At amazon.com, 120 grit for aggressive material removal. Click the image to purchase
Members have had great things to say about John Britt's new book, Mid-Range Glazes. Click the image to buy from Amazon.com
Purchase Glazes Cone 6 by Michael Bailey, The Potters Book of Glaze Recipes by Emmanuel Cooper, or Making Marks by Robin Hopper, all available at amazon.com. Mastering Cone 6 Glazes by John Hesselberth & Ron Roy is now out of print.
Harbor Freight is a great place to find unbeatable prices for better HVLP spray guns with stainless steel parts and serviceable economy models, as well as detail guns, all tested by our members for spraying glazes, as well as compressors to power the guns. As yet no one has tested and commented on the remarkably inexpensive air brushes at harbor freight.
The critter siphon gun is a spray alternative that is well liked by some of our members, and is available at amazon.
Amazon is also a competitive source for photo light tents for shooting professional quality pictures of your work. They also have the EZ Cube brand favored by several of our members. You might also want to purchase the book Photographing Arts, Crafts and Collectibles . . .
If you are up to creating videos of your work or techniques you might want to invest in a flip video camera

ebay is a great alternative for many tools and the equipment used in the ceramics studio - kilns, wheels, extruders, slab rollers are often listed there both new and used.
If you just want to spout off, it is best accomplished as a blog posting. If you want to get more guidance and ideas from other members, ask a question as a new discussion topic. In the upper right corner of the lists for both types of posting, you will find an "+Add " button. Clicking it will open an editor where you create your posting. 4/16/2014
