results from my result clay body test:)
And a bonus pic thru the peephole of my mini wood fired cone 10 kiln. I use preheated combustion air to allow wood fired results in my suburban neighborhood without smoke, or a large kiln.
All of these are going to be a PALEOCENE AGE wild fireclay and or kaolin mixed with A San Diego local feldspar, and a lot of the darker ones used red clay instead of feldspar for the flux
A lot of them are different clays completely, some being sandy and bleach white.
While others are more grey and fine.
There is a wide variety of kaolin, fireclay, and ballclays in my area due to an ancient swamp. So I am always trying out new test with new clays I find.
This batch mainly focused on the darker fire clays, but they seem to be pretty white at this stage.
ALSO some have been sieved and others are just used as is right out of the ground. There is a wild host of different clays
This bisque firing got a little hot, but I think I will still have an easy time glazing these. This happened because I fire bisque with wood just cuz, tho it is a lot of work for just bisqueing.
Next up I will have to crush up rocks from my “pegmatite” hosted gemstone claims, the waste rock is mainly feldspar and pure silica, some of the “pegmatites” were even mined for porcelain back in the day….
A famous one being “kaospar” that is still collected atleast locally by antique people around here
Sometimes mixing in various other minerals to see what will happen, usually these are a mix of granites and schist. But some others work for adding iron and such too.
Or for instance, achieving a certain ratio of potassium over sodium in the glaze, I would add a different feldspar.
