This slip-transfer method also looks interesting:

Somebody mentioned Paul Wandlass earlier, here is some more info.

BTW are you sure that you want to print glaze rather than slip/underglaze?

Forgive the digression, but have you considered paperclay? I am under the impression that several sculptors

had found paperclay a useful and relatively forgiving medium.

H&S point, at a demo by Ian it was advised to remove any bubble-wrap or balloons from the figure before firing

[if fumes were a concern]. Let figure firm up, cut an access hatch, perform bubble-ectomy, replace hatch.

From the earlier thread

http://community.cer...ge-2#entry64648

I am unbelievably proud to say that all of the clay being used for the project is supplied by Potclays and is called Etruscan Red (Sanded) (159-1139S) it's a slightly sanded, red earthernware clay that is being fired right up to 1280C (very high given its recommended maturity is up to 1260-1270C).  The poppies have been finished in a number of ways but the bulk are being fired with a high temperature red glaze identified just for this project - Poppy Red.

 

 

 

BTW talk of a base coat and a top coat might suggest the use of two glazes, but the quote from Chilly's ref is:

Finally the flowers are dipped twice into a scarlet glaze – a base coat and a top coat – and placed back into the kiln where they are heated to 1,117C.

Am I right in thinking that the glaze is diffusing/blurring the mocha pattern on the bisqued slip?

 

If so, you might consider trying mocha diffusion into slip using stains as colourants. These should

resist any solvent effects of the the glaze better than oxides/carbonates.

 

If not, are you sure that you want to mocha onto the top of a glaze, which will melt and encourage

movement, rather than onto some sort of self-glazing slip?

 

Regards, Peter

 

I've only tried a few mocha test-pieces, some years ago. I failed to get mocha patters large enough 

for my decorating ideas and lost interest, but had no problems with glaze-induced blurring -- so it's

not inevitable.

 

If you are using iron oxide as colourant you might look at Cardew's iron red (minus the iron) as it is

intended not to disolve iron. (Book not at hand, full details if you want them.)
