Pair of turquoise and coloured glass discs in wooden frames and stands, 1745-1755.

Pair of coloured glass discs, c. 1750. These glass discs were used by Dr. Stephen Demainbray (1710-1782), lecturer on natural philosophy to King George III, in his lectures on colour. Demainbray toured Britain and France between 1749 and 1754, giving public lectures on natural philosophy. In lecturing on the topic of colour, he was able to glorify Isaac Newton's (1642-1727) theories on the spectrum, and treat the theories of his rivals 'in a candid manner'.
