When processing minerals in a furnace, materials can either be melted or sintered. When materials are melted during the production process the minerals go from a solid state, to a liquid state, then is re-solidified during the cooling process creating uniformity in the chemistry throughout the entire batch. The sinerting process heats the minerals in the furnace to two-thirds the melting point creating a spongy state. In the spongy state, materials can “stick” to each other and re-harden as a bonded pair. Sintered materials are not as uniformed, strong or pure compared to materials that are melted.
We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost.
