Hi Lisa,
What about the different colored Brazilian clays? Are they just kaolin with color added or do they come from the earth naturally colored?

Hi Juanita - The colored Brazilian clays I have seen on the market are a mix of Montmorillonite, Kaolin and Mica. I have not yet come across a Brazilian clay that is different from any of the clays in this guide. Mind you, I'm always willing to learn, so if you have some sources to share, please do leave a comment! :)

This is an excellent guide. I was wondering if using superfine clays, like kaolins (3 microns
particle size) would be like using nanoparticles since probably the 3 micrometer is the average particle size and there could be some that are smaller. I can't find any information about this anywhere. What do you think about this?

Hi SnowyOwl - Thanks for your input! Using superfine clays down to 3 microns is still not small enough to be classified as nanoparticles. 3 microns is equivalent to 3000 nanometers, so you're ok using superfine clays. Of course always be mindful of the dangers of inhaling powders. It's always a good idea to wear a mask when working with powders. :)
Hi Lisa Lise,

Wonderful clay article!

I have a question concerning clay and metal. I've received controversial information, on one hand I've read on that one should not mix clay in a metal bowl, or with a metal spoon, including stainless steel, on the other, I've also been told that this was not an issue, someone once said this and everyone followed suit and regurgitated the misinformation.

Have you looked into this, does using a metal spoon, or bowl actually have an effect on the product. If there is an impact is it only the hydrated clay, or will it affect dry clay as well?

Hoping you have further information related to this topic!

Take care.

Hi Geneviève - This is a great question. I recently heard about a clay mine that uses only wooden tools to mine their clay so as not to interfere with the natural mineral content of the clay. I would have to look into this a bit more before answering you in detail, and do have a couple of posts on clay coming up. Please bear with me while I check on this furrther :)
