Fireclay crucibles, magnesite cupels

For assay analysis of precious metals from non-ferrous ore concentrates. Crucibles and cupels are used for heating, drying, burning, calcining or melting various materials. They are an integral part of metallurgical plants and factories for casting various metals, alloys, etc. A feature of crucibles is the use of refractory materials for their creation and high resistance to various effects of metals and alloys. Fireclay crucible, volume 0.5 liters.
