Madras® exclusively by Vitrealspecchi
A glass dated 1686 is the earliest specimen we have of chemically etched glass. Experts attribute it to Heinrich Schwanhardt, son of George the master engraver. Heinrich used acid to obtain glass with sparkling designs standing out against an opaque background.
The technique only started to spread in the mid 19th century, when it was used by Emile Gallé, but given the complexity of the “know-how” involved, it was passed down jealously from workshop to workshop, from one master glassmaker to another.
It was only in the early 1960s that the technique was taken up again and developed on an industrial scale, by Vitrealspecchi, which patented a process for satin-finishing and decorating float glass. It chose the name of Madras® for this type of glass because the wrinkle effect produced by the etching recalls the sheen of a particular Indian silk making technique.
