Basic evening-class stuff, but a test tile with a stripe of each on N glazes one way,

overlain with a stripe of all the colours at right angles shows you the effects of all

N glazes under/over all the others. I wouldn't try with N=40 though!

...  a blank line in one direction [so an Nx(N-1) grid] shows single and double 

coverage of each glaze as well.

Quote: Another interesting thing though, the tests with only one opacifier didn't break
red the way it does with both tin and superpax.

In Topic: Naked Raku - Resist Slip Falls Off Of Bisque

01 August 2014 - 07:38 PM

Hi, When doing 2-part naked raku I've always used a special purpose resist slip

containg 1 part flint and 2 parts china clay (by volume). A little food colouring may

help to see missed bits when covering this with the crackle glaze.

 

I've always tried to fire the pieces bone dry (drying them on top of a kiln if necessary). In

my experience it doesn't take much moisture to cause a pot to explode in a raku firing.

 

It's usual to wave the pot about a little before putting it into the reduction bin, to ensure

that the glaze has started to crackle.

 

Regards, Peter

 

I've never been able to get hold of the right fireclays, so have never tried one-part naked

raku. From reading about it, I get the idea that it is a very different process. So it may be

best to avoid trying to mix-and-match ideas from the two processes, at least at first.
