Item Name:
Boron Nitrate Spray - 10oz
SKU:
44110
Description:
Boron nitrate spray is a specialized release agent formulated for glass fusing and slumping applications. This product is manufactured as a liquid suspension that is applied via spray bottle, creating a thin, even coating on kiln shelves and glass surfaces. The boron nitrate compound forms a barrier that prevents molten glass from adhering to shelf surfaces during high-temperature firing cycles. In fusing work, boron nitrate spray is essential for protecting kiln shelves from glass drips and ensuring clean releases of finished pieces. The spray application method allows for precise, controlled coverage without the mess or waste associated with brush-applied release agents. This product is particularly valued in both artistic and scientific glass fusing where shelf protection and piece release are critical to successful outcomes.
How it is used:
Boron nitrate spray is applied directly to clean kiln shelves before placing glass pieces for fusing or slumping. The spray should be applied in light, even coats, allowing each coat to dry before adding additional layers if needed. For best results, apply the spray in a well-ventilated area and allow the coating to cure fully before introducing the shelf into the kiln. During firing, the boron nitrate creates a non-stick surface that allows finished glass pieces to release cleanly without sticking or requiring aggressive removal techniques that could damage the work. After firing, any residual boron nitrate coating can be cleaned from the shelf with water or mild scrubbing, preparing the shelf for the next use.
