Pictures are often informative. Have a look at the Slow Cooling article in the freebie at:

In Topic: Color Depth For Stains At ^6 On White Stoneware

Tried degussa red? One part stain, four parts gerstley borate. It smells like raunchy egg farts, but gives a beautiful red...


Err do many of your glazes smell?


The cadmium colours come from cadmium seleno-sulphides. Both sulphur and selenium are notorious for producing

smelly compounds (like rotten eggs, garlic, ...). But they should be safely encapsulated, shouldn't they?

Mark: thanks but I'd already managed to get access to the Deformations and Tensions article.

I'd thought that Nerd/Tom was referencing another article in the same journal, and I was majestically

failing to find it.


Nerd: thanks, found it.

Was reading article from a science/technology resource on clay body formulations. Found it very interesting that they are beginning to move away from the Seger Unity Formula into percentage levels based on "light", "medium" and "heavy" kaolin and ball clay. Noting a maximum of certain minerals such as FE @ 3%. Curious to see what new formulation methods they end up adopting.

Sounds very interesting, but I'm having problems finding it. Would it be possible for you to post the articles title?

I couldn't find it in the March 2016 issue your link takes me to, and I'm having no luck with the search facilities.

Titles like Understanding Clay Body Formulation sound promising, but I can find little mention of kaolin and none

of heavy/medium/light forms (whatever they might be).
