Test 1

Here is the first of my tests for a great Egyptian Faience clay body:

Here are the fired results
(cone06):

Methods: (notes to self...)

Base batch all include .5 part copper carb
add:
1)  base
1.5)  base + 1/4 pt mason #6266 (peacock green)
2)  base + 1part ball clay for plasticity
3)  base + 1/2 pt ball clay + 1/4 pt neph sye.
3.5)  same as #3 but rolled into a slab and placed on a slab of lowfire slip slab, joined and pressed into a mold.
Results:  
1= good but non plastic, cracks develop
1.5= bad....mason's too dark
2= ok, not as shiny as 3.
3= great, best result.....color could be darker for more tests...
3.5= very interesting direction, esp. the thick/thin color variation
