A Short History of HUNTER REFRACTORIESHUNTER brand cupels are manufactured in Sparks, Nevada (USA) using the highest quality domestic magnesium oxide or bone ash.
We have served the needs of assay laboratories in the Western United States since 1983 and now serve our East Coast customers through our facility in Holliston, Massachusetts.
Our cupels are tested daily to ensure that they meet our rigid quality specifications. They are consistent in hardness, porosity and density, so as to provide uniformity in cupellation and give lower precious metal losses.
HUNTER cupels have the ability to absorb their own weight of Litharge.
HUNTER cupels are conveniently packaged for safe shipping and ease of handling at your facility.
