Fire Clay, Fireclay, Mortar Clay and/or Bricklayers Clay is an organic material that has been dried and turned into a powder form. It is usually a brackish red / brown in color or it could be white / grey. The texture is like baking flour or baking soda.
These powdered clays can be found at most Masonry and Landscape Supply Stores for about $10 per 50lb bag of firing clay (also see companies below).
You may find a bag of fire clay at a Big Box hardware store like Home Depot, Lowes or Menards - but it’s unlikely.
