Fiber Mold Hardener


Pour this liquid over ceramic fiber products to give them rigidity. Can be used with fiber paper, fiber board and fiber blanket. To use, simply burn out any of the binders that may be in the fiber product by firing it to 1200° in a vented kiln. Saturate the fiber with the mold hardener and kiln fire or air dry. The resulting durable fiber forms can be used for bending molds, support walls or other high temperature forms. Great for making drop-out rings.
