What is Black Clay?

Black clay is a type of pottery clay that is naturally dark or made darker through the addition of certain materials. It is prized for its striking appearance and is often used in creating decorative pieces and functional pottery.

How to Make Black Clay at Home

Creating black clay involves mixing natural clay with specific oxides or stains. Here’s a step-by-step guide:

1. Gather Your Materials:

   • Adjust the colorant ratio if necessary based on the test results.

6. Store the Clay Properly:

   • Keep the clay in an airtight container to prevent it from drying out.
