Vinegar is used to re-hydrate the clay without adding excess water which would cause the rim to expand and crack. It's often used to join handles to mugs and other such appendages in ceramics...We refer to it as Unicorn Pee because of its apparent magical properties! Hope that helps!

Thanks for your teaching, but I'm more interested in how to prepare a good slip for my slip casting process. I don´t know why there are not videos to teach that to the artisans. The final product is a result regarding each earlier steps throughout the process. I don't know to learn about WHAT or HOW but WHY. ¡Thanks again!

Wonderful video! Does anyone know if it's possible to do this with a cylindrical cup, instead of a cone? I mean, if the walls of the cup are parallel, will it come off the mold easily?
@theabristlebroom43782 жыл бұрын
It is unlikely to come cleanly out until it has dried to close to bone dry. This may work for you, but for most potter's would not like it that dry.

For the most common formulation of slip (no idea what that is), what is the density of the finished fired material? I'm asking for the density of a simple formulation without additives to achieve porosity. If there is a reference page of material properties you can suggest, please do.

@ozmoderntx47186 жыл бұрын
if you left this in the mold would it dry completely solid? and how long would that take? thank you
@patthebackyardbuilder4215 жыл бұрын
The clay shrinks as it dries. My guess is that if you let it dry until it was solid, then at some point the casting would crack. The reason for this is the item would dry from the outside to the inside and the drying would thus be uneven. This normally happens when you pour the item, but when the item is thin (because you pour out the excess slip) then the item is able to dry somewhat evenly, reducing the stress on the clay.

@theabristlebroom43782 жыл бұрын
Not with clay. Plaster is used with clay to absorb the water in the clay, drying it. Wood can pull some water out, but not enough and it is slow. Foam would not absorb water, so that is right out.

Where is the handmade element to slipcasting pottery?
@WantingMemoriesLJM9 жыл бұрын
+stephen ryan Well, often the potter has constructed the original piece from which the mold is made. Many who sell their work, find that they can mark down prices significantly on cast pieces, especially compared with slab built boxes or rectangles, and so they can successfully sell more. Additionally, what if the cup isn't the emphasis? What if the artist includes decoration that takes hours such as piercing, sculpting, or fine glaze techniques? This all adds up in time put into a piece, which means a higher cost in sales...
