#54737 Struggles Developing Clay Body From Local Clay

Posted by Rockhopper on 15 March 2014 - 02:05 PM

Update:   after much trial & error - 60+ recipe variations, 100+ test tiles, and failed pots ranging from crumbling to melted - I have a useable clay body.  Still need to tighten it up a bit before I can use it for vases & such (paper towel placed under bowl filled with water, gets damp pretty quickly) - but at-least my pots aren't coming out of the kiln looking like lava :)

 

Current mix;  Local Clay 41.5%, EPK 35%, Silica 15%, Custer Spar 8.5%

These two show the wide surface, middle portion of the two pieces.  4) Shows tan and RR side-by-side and overlapping in center; 5) un-glazed strip

Here are some close-up pics.  Not quite pro-quality macro, but as good as it gets with my Canon powershot..

 

The first three are cross-section of broken test-strips.  1) Un-glazed;  2) RR end of glazed piece; 3) Tan end of glazed piece.  (2 & 3 are opposite ends of same piece)
