  • 100% Powdered Fire Clay for High-Temperature Mortar Mix

Fire Clay - High Temperature Mortar Ingredient


Product Description

Pure Fire Clay, 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 - $15 per 50lb bag of firing clay. You may find a bag of fire clay at a Big Box store... but it’s unlikely.  And you will never find fire clay at a Refractory Materials Dealer.


If you can’t find a bag near you, check with your local Ceramic Supply and they can order a bag of Fire clay for you.  If all else fails - we can always ship you a bag of Fire Clay 2.


If all else fails - we can always ship you a bag of Fire Clay.  We've got plenty in stock...
