Sandblasting is yet another technique used in glass engraving. Abrasive is sprayed through a sandblasting gun on to glass which is masked up by a piece of stencil in order to produce inscriptions.

Glass engraving is considered by many to be a dying art form. While this is far from accurate it is certainly a form that has seen its heyday come and go. Despite this there are still many glass engravers who are producing bold dynamic and aesthetically challenging artworks. In the UK one of the most notable artists is Alison Kinnaird MBE. Based in Scotland she splits her time between glass engraving and playing the traditional Scottish harp. In recent years these two apparently disparate mediums have been combined when she composed music to accompany her piece "Psalmsong" which is now installed in the Scottish Parliament building.

The UK currently has a Guild of Glass engravers based in London and lists a number of well respected glass artists as members, including some overseas. These include Katherine Coleman MBE, Sally Scott, Tracey Sheppard, Dominic Fonde and Ronald Pennell. It has an online gallery of members works with contact details for commissions and classes for people who want to learn about this art. A general exhibition is held every two years. This is currently at
the FitzWilliam museum in Cambridge from 15th June to 15th August. Local branches in the UK meet for joint practical work, tutorials, and hold regional exhibitions.

Meanwhile the Czech republic having produced many world class glass artists can lay claim to one of the very best, Jiri Harcuba. Every two years the Czech Republic hosts a conference aimed specifically at glass engravers. Other prolific notables around the world are Kevin Gordon in Australia and Lisabeth Sterling in the United States.

Some artists, such as Lesley Pyke, combine the art of hand engraving with sandblasting for not only collectible work, but bespoke pieces which become family heirlooms and every day commercial requirements such as corporate presentations and sporting awards.
