Ed Murray and Jack Devlin started this business and created Murlin Chemical, Inc. to produce Mold Lubricant. Murlin Chemical had sold this product under the name “Synthetic Bone Ash.” The world wide use of Mold Lubricant/Mold Coat reached five to six thousand tons per year in the 1960’s. However, with the advent of the “ Continuous Cast Rod System” in the 1970s, it reduced the demand for Synthetic Bone Ash. As this technique became widely known, its economic advantages became strikingly apparent. As the use of Synthetic Bone Ash declined, Murlin began to explore natural products.

 

Natural Bone Ash became the lead candidate as it was readily available.  A search for bone products eventually led to the production of the superior bone ash we manufacture today. Murlin Chemical made it's first shipment of natural bone ash in late 1981.

 

Over the years we have made numerous advances in the processing of natural bone ash that has resulted in the premium products we offer. The largest use for Murlin Natural Bone Ash is in the Aluminum industry where our Aluminum Grade product is the material of choice at most foundries. This product is used to coat refractory troughs and parts of the equipment used to deliver molten aluminum to direct cast ingots, as a coating on furnace tools, dross bins, dross coolers, furnace fronts, floor level crane rail, spouts and pour points. Bone Ash packs well and is frequently used to plug potential leaking spots in metal transfer systems. Aluminum foundries advise that bone ash will not contaminate molten aluminum during a cast. If the bone ash comes loose from its coating or as loose material in the trough, this loose bone ash floats into the oxide coating of the molten metal and remains in the skin after the cast is finished.
