s the technique of forming an object by inflating a gather of molten glass on to the end of a blowpipe. The gaffer blows through the tube, slightly inflating the molten glass. This is then manipulated into the required form by swinging the blowpipe, rolling the gather on a marver, or shaping the gather with tools or in a mould. The manipulated gather is then inflated to the desired size.
