badmintonsyd Posted March 25, 2013 Report Share Posted March 25, 2013 I've been using my own porcelain paper clay recipe for the past year or so. I love how it looks once it's fired, but I'm having issues working with it wet sometimes. I have a feeling it might be the ratio for paper to clay that I've been using (I think I'm working with 30-40% paper). Anyone have any advice for me? Should I try another kind of fiber? ( For the paper, I just use single-ply toilet paper) Link to comment Share on other sites More sharing options...

( For the paper, I just use single-ply toilet paper) That seems like a high % of paper. My understanding is a maximum of 25%. Use anywhere from 15-25% Marcia Link to comment Share on other sites More sharing options...
TypicalGirl Posted March 25, 2013 Report Share Posted March 25, 2013 I typically use 10% - 15% ratio. Link to comment Share on other sites More sharing options...

clay lover Posted March 26, 2013 Report Share Posted March 26, 2013 How are you guys measuring the paper, and is it wet clay by weight? I have only used paper clay for joining slip and then just threw a few sheets of toilet paper in a blender made a slurry, and then added bits of wet clay until it 'looked right'. Is there a more accurate way to figure the ratio. Can't imaging weighing toilet paper, may be too early in the AM for me to grasp this, need more coffee.

How I did it was I made a paper slurry, then dried it so I had paper "pellets" and then measured from there Link to comment Share on other sites More sharing options...

TypicalGirl Posted March 26, 2013 Report Share Posted March 26, 2013 Honestly, I just guess. Porcelain paper clay is the only kind I mix myself, my stoneware is a commercially produced body that contains 10%-20% paper, depending on the body. With the porcelain, I mix a slurry of toilet paper, water and bleach and then add it to the clay (which I've made into a slip). No more than 20% paper, and its strong enough to withstand raku.

Marcia Selsor Posted March 26, 2013 Report Share Posted March 26, 2013 For patching I use a paste made in a blender with toilet paper or bits of paper from dried orange size paper that was made into pulp and strained. For working with paper clay I mix in a Soldner mixer and ad by dry volume. Marcia Link to comment Share on other sites More sharing options...
Sandra Jimison Posted March 31, 2013 Report Share Posted March 31, 2013 Where do you find paper clay commercially? I have never used paper clay, because the process seems to intimidate me, but from what I've read I know I should. If I could buy it, all the better. Sandra Honestly, I just guess.

How fine are we talking about, I never thought of that. I will be up-grading my patching slip. Link to comment Share on other sites More sharing options...

I thought paper clay was great for sculpture for two reasons. First being as stated in the clay descriptions, is low shrinkage, but second an incredibly smooth texture for good fine details like you naturally get with porcelain. The grog confuses me. On this same note, what is B mix? Thanks for your patience. Sandra Link to comment Share on other sites More sharing options...

How fine are we talking about, I never thought of that. I will be up-grading my patching slip. In order to measure by volume, the paper slurry needs to be compressed. I strain it and get rid of the water and squeeze the remaining pulp into orange size lumps. Then, I can look at the dry volume and estimate 15%. For large quantities I am not using tp but paper linter. Marcia Link to comment Share on other sites More sharing options...

Diana Ferreira Posted April 16, 2013 Report Share Posted April 16, 2013 I use 2 toilet rolls in a bucket of slip. Casted some really awesome and thin work with it. I was able to really break down the paper with my 'blender tool bit on the drill' and got a very smooth mix and a smooth slipcasted end-result.
