Melting vessel

A runaway decomposition in a melting vessel associated with distillation of the crude product burst the vessel and led to a major fire. The short report does not include detailed circumstances. The decomposition was attributed to the catalytic effects of impurities. However, it seems that nitric acid was also present. 

BONUS BARBOTUS — Vessel for melting — Vessel into which liquids are poured from above — - Vessel for mixing —joined for the operation of fusion. 

CATILLUS CINEREUS — is a Melting Vessel with two parts of moistened cinders of light wood, purified from all ashes and other dirt and with one part of cinders properly ground out of bones that have no marrow [let not these bones be taken from pigs because they are so expensive] which have been reduced into a paste or mass, and properly mixed together in a mortar. Let this mortar be filled with moistened cinders, and the pestle, which is commonly called monachus, is hammered into it with three blows of a wooden mallet, and let there be cinders put inside, by means of a hair sieve, from the head of a calf. One or two blows may be added with a stag s horn. Then let the matter be removed and dried. 

CRUCIBULUM — is a Melting Vessel, made of some earth which can absolutely withstand fire it has a narrow base, and widens out into a round or triangular body it is used for melting and liquefying metals. There is also a species of crucible which is vulgarly called a Cupel, and is adapted for melting metals.

The raw materials are melted at temperatures of 1200 to 1600°C in tank, cupola, electric arc or electrical melting units. Tank furnaces similar to those used for the manufacture of glass are used for the production of glass wool. The melt vessel is a large rectangular tank with the mixture added at one end and the melt taken off at the other.
