Hello,
My apologies if this is the wrong place for this post,
I'm very much a beginner but have taken two ceramic courses. They are not keen on teaching you about porcelain, which is why I thought I'd take matters into my own hands and teach myself, as it is the only clay type I'm interested in (even though I'm told it's too difficult for beginners, I'm stubborn and like it way too much not to start working with it). I want to try slip casting as an affordable wheel alternative and for a change, and would like to attach my hand sculpted pieces (tiny humans, animals, leaves) to, for example, a slip casted mug, to create some sort of fantasy scenery mug. I'd also like to paint details on them with homemade underglaze, and I wondered if it would be a good idea to make it out of the same clay used for the sculpted pieces. Dried, ground up and mixed with high temperature pigments in the right proportions, and then made into a slip. But both the sculpted clay and the engobe would need to have the right shrinking percentage for the slip casting clay. I can't find too much information about it online. Is mixing these two mediums possible or too much of a risk? The clays sold do come with the percentage.... but is it really this simple?
Could I dry out the pre-made liquid slip clay slightly, and use that for sculpting as well? Or will the slip ingredients make it less suitable to work with in that sort of way? Merely a matter of trial and error?Ahh! I have no idea....
