*Please be aware that natural impurities may occasionally occur in our clay! Our clays are made with natural minerals, mined from the earth. In some rare cases, natural impurities, or ribbons of other minerals, are mixed in with the raw materials provided by our suppliers. This can lead to clays that don’t perform the way they are supposed to. If you have any questions about a particular clay body, please reach out to info@seattlepotterysupply.com.
