BY BILL DAVIS, THE JOHNSTON COLLECTION
The Dutch excelled in engraving glass with a diamond point, both with line engraving where the image was scratched in lines on the glass surface, and with stipple engraving where the image was developed by pitting the glass surface.
There are some examples of line engraving on 17th century English glass, but unlike Continental practice, little English glass was decorated during the early part of the 18th century.
