Heat-treat Hot Rack

Our hand-mixed and poured refractory Hot Racks will keep your work off the kiln floor and allow even heat around each piece. Heat treat your blades upright in this rack and never look back.  Each Hot Rack has four slots to hold your blades - no stacking necessary. If you have the room and the need for it, double up and heat treat in batches of eight! *NOTE: you'll want to pre-heat your Hot Rack in the kiln at the start of each session* Material: Kast-O-Lite 30 LI Plus refractory Temp resistance: Rated to 3000°F Dimensions: 6"L x 4.25"W x 2.25"H (approx.)
