In Topic: Milk Bath?

Today, 06:34 PM

 

I am trying to figure out what substance in cow's milk would not burn out in a firing. It is only about 70 miles from Kiev to Chernobyl.


Back a bit, we had this thread w/videos. The Tibetan potters sealed their low-fire wares with a mixture of barley powder and yogurt whey.

Wonder if the Ukrainians are using raw, unpasteurized milk? And, would chocolate milk give you a tenmoko?

 

 

So, do you think it would work like an old school casein glue to seal the inside? Maybe something else mixed with milk? With the translation of the second link from Stellaria it seems like the milk is fired into the pot. Perhaps it is just a very low carbonization of the "glaze" turning the pots blackish? Prices seem dirt cheap, (pun intended) but then I don't know the cost of living in that part of the world.

 Interesting article http://cultkiev.com/...aven-born-craft .

Radioactive calcium and magnesium?  ;)

Any chance you cracked the lid while the kiln was still hot? My guess is that it looks like a cooling dunt perhaps in combination with having a thick glaze layer on what looks like a very thin clay thickness.


In Topic: Feldspar Substitutions?

You could probably just sub the minspar 1:1 for the soda spar. Was it F4 you were using before? If so and you want to get picky with a very close match the new recipe would be:

 

Minspar 200    41.6

Epk                   6.1

Silica                24.9

Whiting            15.2

Zinc                 12.2

 

total:                100

 

titanium            5

copper carb     5 

 

When I just use soda feldspar the rebalanced recipe would be;

 

Minspar    41.2

Epk            6

Silica        25.6

Whiting    15.1

Zinc         12.1

 

total:    100

 

titanium          5

copper carb   5

In my recipes that used K4 I am now using Minspar. There is a bit more silica in Minspar, the rest of the chemistry is fairly close. If you don't use a glaze program then myself or someone else here could do the conversion for you if you post your recipe.
