Originally, the mirror was made of polished metal, but it is said that in Egypt and in the Roman period before Christ came mirrors formed by glass sheets accented to a pond or silver, just as it is certain that a silvering was used in Roman times i nside glasses and cups.
In 1507, Andrea and Domenego dal Gallo of the glass factory "del Gallo" in Murano, pointed out a technique to lay a slight layer of tin over crystal plates. This technique enables to achieve a manufacture privilege (a sort of patent granted by the Council of Ten in the Republic of Venice) for a period of 20 years.
Between 1534 and 1554 , a manufacturer of metal mirrors - Vincenzo Redor - will develop a technique to smooth crystal plates to confer the same reflection degree of metal mirrors to glass mirrors . Such an exclusive technical evolution will be “patented” and adopted by Redor for 25 years.
The manufacturing technique consisted of silvering with tin and mercury amalgam and, later, with a silver or platinum deposit on a plate ootenuto of the hot longitudinal cut, naturally (with the consequent opening and spinning), of a glass bubble blown.
However the artistic engraving skills remained, allowing Venice to remain, as it still does today, a point of reference in the production of decorative mirrors, not just in Europe but all over the world.
