Johnson would remain in business for himself for the next 34 years until George Matthey joined the operation in 1851 and the name was changed officially to Johnson & Matthey. The company quickly earned, by 1852, an appointment as the Official Assayer & Refiner to the Bank of England.

Typically an induction furnace is used to heat the metal to its melting point, at which time the holding crucible is tilted to transfer the molten metals through a soft gas flame and into a pre-heated and dressed bar mold to create the bar’s specific size and weight. To ensure proper weights are reached, the molds are typically positioned on a balance to record the weight of the metal as it is poured so that pouring can cease when the right weight is reached.
