AL CORE body binder
A ceramic body binder for black core removal. Send us a photo of your broken tile edge and your firing cycle, and we will suggest a grade and a starting dosage.
What black core is
Black core is a dark band inside a fired tile. Carbon from clay organics and additives uses up the oxygen in the body, iron oxide is reduced, and the reduced iron melts into the body.
It gets worse when the body is pressed too dense to breathe, when a fast cycle leaves too little time, or when a glaze that softens early seals the surface. Besides the mark at cut edges and chamfers, it can bring swelling and lower strength.

Why the binder matters
A body binder raises green strength, dry strength and edge strength, so tiles survive the trip from press to kiln. Organic binders also add carbon that has to burn out. Lignosulfonate is the known example: it can sharply raise pressed strength, and black core often follows.
The AL CORE series is a body binder for plants that need strength and core removal together. The right grade and dosage depend on your body and cycle, so we set them against your numbers.
