Bonnybridge brick found in Rio Grande do Sul, Brazil.

Found by Tassiane Freitas in Rio Grande do Sul, Brazil.

Tassiane states  – “This brick was found in the backyard of my house in Arroio dos Ratos. It was probably removed from the building of the old thermoelectric power plant in the city (The first one in Brazil, which is 1924 and was dismantled in the 1950. This subject you can know more by reading my master thesis –https://wp.ufpel.edu.br/ppgmp/dissertacoes/2/ ).
Today the old thermoelectric plant is the State Museum of Coal (https://www.facebook.com/museucarvao/) and Historical Archives of Mining, the largest and most specialized archive on coal mining in Brazil that is known.
English and Germans were in Arroio dos Ratos for the construction of this plant. Probably this information has a relationship with the presence of Bonnybridge bricks around here.”

Hepworth Ceramic Holdings plc (GR-Stein Refractories Ltd. parent co) bought the Bonnybridge Silica & Fireclay Co. Ltd in 1972, closed Bonnybridge works in 1973 and closed Chapelhall in 1980. Therefore between 1972 and 1980, GR-Stein Refractories probably continued to manufacture bricks with this trademark for a time.
