      Moderators needed!   12/08/2017

      Ceramic Arts Network is looking for two new forum moderators for the Clay and Glaze Chemistry and Equipment Use and Repair sections of the Ceramic Arts Network Community Forum. We are looking for somebody who is an active participant (i.e. somebody who participates on a daily basis, or near daily) on the forum. Moderators must be willing to monitor the forum on a daily basis to remove spam, make sure members are adhering to the Forum Terms of Use, and make sure posts are in the appropriate categories. In addition to moderating their primary sections, Moderators must work as a team with other moderators to monitor the areas of the forum that do not have dedicated moderators (Educational Approaches and Resources, Aesthetic Approaches and Philosophy, etc.). Moderators must have a solid understanding of the area of the forum they are going to moderate (i.e. the Clay and Glaze Chemistry moderator must be somebody who mixes, tests, and has a decent understanding of materials). Moderators must be diplomatic communicators, be receptive to others’ ideas, and be able to see things from multiple perspectives. This is a volunteer position that comes with an honorary annual ICAN Gold membership. If you are interested, please send an email outlining your experience and qualifications to jharnetty@ceramics.org.

I have just acquired a bit of Spencer throwing clay. Never heard of it....believe it said mfg. in Seattle. It is very old dry and was stored under a house...all or most of the labeling is gone from the boxes... but some is marked LLM..and others have an SMY label ... the SMY is yellow in color...not buff but yellow. another is redder than an earthenware...or so it seems to me. The LLM is offwhite. Anyone know what type and cone(s) these clays might be? Whats the best way to figure out what I have (after I reconstitute these bricks ... HAH.) . thanks.

Here is a start. It's a freemium from ceramics arts daily. "Successful Tips for Buying and Using Pottery Clay: How to Select, Process, and Test Clay Bodies for Better Results" google it

I've been reading up I'm about to make clay for first time.

 

Since its very unknown I' d build. Catch tray for tests. So you don't end up with a mess in kiln.

I found this while searching about...

 

 

"Deb Barrett asked about the clay I used for the demonstrations in the book. It comes from Clay Art Center in Tacoma, WA. Here's the description:

 

CL043 SMY - MID-RANGE STONEWARE CONE 4-6:

 

Yellow iron gives this general purpose clay body a ...golden appearance when wet. It fires a warm light brown in oxidation and dark brown in reduction. Fine textured with 70 mesh sand. Cone 4-6. Wet Color golden, Oxidation Color light brown, Reduction Color dark brown, Texture medium smooth, Shrinkage 13.0%, Absorption 0.5%."
