Intaglio cutting was a new style of cutting introduced about 1891 with the utilisation of steam power. It was a technique exploited to the full on coloured transparent glass in designs created by Frederick Carder and executed by Joshua Hodgetts and John Orchard at Stevens & Williams.
Although also employed by Thomas Webb & Sons the technique was used by them more to enhance their rock crystal than to compete with S&W’s coloured ranges.
The technique and development of intaglio cutting in Stourbridge was described by John Northwood II in his book “John Northwood. His Contribution to The Stourbridge Flint Glass Industry 1850 – 1902.“.
