Potters & Sculptors - Making Rock from Mud
Comment
There is a Yahoo group called potterybasics of which Ron is a member. You could join and post the question to him. He is very good to share his expertise.
I am using the Mastering Cone 6 Glaze book as well. However, several of the formulas call for G-200 Feldspar which is not sold in my area. Does anyone else substitute Custer Feldspar for the G-200?
Ron gives one hint which was for his Glossy Base Glaze 2 with Custer Feldspar. He indicated if you use G-200 then you need to reduce IPK by by 1% and increase silica by 1%. If the reverse is true then substituting Custer for G-200 would seem to be the opposite. Anyone using the Custer instead of G-200 Feldspar?
Thanks Tracy! I love that book, I also use the GlazeMaster software which really helps one to analyze before testing. Thanks for sharing!
The clay is Standard 200, and the glaze is spearmint from Mastering Cone 6 Glazes. Most of the base glazes I use are from that book- I love it. I sub titanium dioxide for the rutile, because the rutile I've been getting lately is really dark and grays out some of my glazes alot. Also, I use 3% copper carb instead of the 4% that is called for in the book. Getting to know your glazes is really important so you can tweek things to get what you want.
Would you please share which clay and glaze you used on this piece. Really great work!
I have not seen a slab plate/tray yet with a flat, unglazed bottom that I like. Not only is it ugly, you are right, it would be impractical as a functional piece because of cleaning, and I cringe to think of what it might do to a table or counter. It's very easy to sandwich a slab between 2 pieces of fabric to texture both sides, and it does create more interest when it's turned over, I think.
One advantage I see is the glazing of the bottom surface, makes not only more presentable but ability to clean is a plus. surprised I was to see it also textured.

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

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
