Crown glass
- a method of producing glass
in which a globe is transferred from the
blowpipe to a pontil or punty, reheated and then spun until it opened up into a large flat plate
- a table of crown glass. It often has a greenish tinge, curves slightly and can have
small radial imperfections, all of which can give the glass a wonderful reflective
quality. While more costly to produce through the wastage associated with its
circular shape, because it does not come into contact with
any surface during manufacture, it is more transparent than cylinder glass.
