I just joined Clayshare, today is my first time watching as premium. I have used this slip recipe without mush success I used it on leather hard plate. It fell apart as i tried to use sgraffito on it. What am i doing wrong??
I guess I didn’t realize there was a recipe for slip. What I did was clean my clay after throwing, sieve it and let some of the water evaporate to get the consistency I wanted. Then I added black stain and put it in the squeeze bottle to slip trail with. It slip trails nicely but it doesn’t dry. That part I did not expect. Why is it not drying? I apply it to bisqueware and then bisque fire again. then add a layer of clear glaze and glaze fire. After that Some of the slip has slightly smudged and some slip is fine. Your thoughts please? Thank you.
Slip trailing is most effective if you apply to greenware well before bone dry stage, and definitely before bisque. I think your clay being at two very different levels of vitrification prevents them from bonding. The slip you made might not have had a chance to bond to itself during the bisque stage, because it wasn't bonded or dry when it went into the bisque- which is very important. Glazes are made with clay in the recipe to make it bond with the ceramic, it is probably mixing with the soft clay in your slip, which makes it melt with the glaze. I hope it helps!
