Ceramic Clay Slip

[Clay Concepts LLC]

Our clay slip supplier has changed their formula and is no longer working for us; they are eliminating talc from their ceramic clay body. We are desperate to find a new supplier of ceramic clay, in bulk, which we can mix ourselves. Thank you.

Hi There!

You might provide some detail (to narrow it down some); if not the particular product (which you were using prior) that has been reformulated, perhaps

  firing temperature(s),
  products/wares,
  glazes,
  problems ("...no longer working..."),
  processes,
  and etc.

The more eggs-act, the better, eh?
 

Is the reformulated product using a different talc?
The magnesium being rather important ...if not, what materials are being used in the place of magnesium?

By "...mix ourselves." do you mean add water to?
Are you willing/able to measure ingredients, then add water and mix?

I'm only using slip from the stoneware clays I'm throwing, a) scraped from my hands, then collected in a bowl to use for fastening handles later on, all clays, and b) blunged with a blender, sieved to remove sand, then allowed to dry a bit - for brushed on accents and brushed on sgraffito layer, red clay.
...just curious, and trying to be helpful.

Thank you for the questions. I just now found out the ceramic industry is in the process of changing to a clay body without talc . That is the problem! Thank you.

@Clay Concepts LLC, it sounds like you were using a lowfire talc body? Is mixing your own body an option? If so are you okay with doing some testing? What’s the problem with the new commercial casting slip? Glaze fit?
