Research Facts
Dr Ralph and Mrs Olga Crawford donated their extensive Canadian dental collection to the DCF to create the museum in 1997; further donations were received while Dr Crawford was Curator Emeritus at the Dental Canada Museum until its closure in 2008; dental silver is used in the creation of amalgam fillings, which consist of 40-50% liquid mercury mixed with one or more metals; amalgams were first used in France in the early 19th century, but the modern 'recipe' was perfected by Dr. G. V. Black in the 1890s in Chicago; the metal usually contains a high percentage of silver (around 70%) and a mix of tin, copper and zinc; high copper amalgams are also available, where the silver content is much lower (as low as 40%) and the copper much more prevalent

Research Facts
Dr Ralph and Mrs Olga Crawford donated their extensive Canadian dental collection to the DCF to create the museum in 1997; further donations were received while Dr Crawford was Curator Emeritus at the Dental Canada Museum until its closure in 2008; True Dentalloy was S. S. White's dental alloy for use in making amalgam fillings, and it consisted of a high percentage of silver (around 70%) and a mix of tin, copper and zinc; amalgams were first used in France in the early 19th century, and involved amalgamating metals with mercury; the modern 'recipe' was perfected by Dr. G. V. Black in the 1890s in Chicago, and S. S. White used his method to create their Dentalloy; in their catalogue they state their alloy is perfectly balanced, meaning the expansion of one metal is balanced by the contraction of another, and tempered, meaning it is aged so that the metals will remain stable
