Staple iron
The staple iron , also known as umbilical iron , is a glassmaker's tool and is an iron rod about 5 feet long to which the glass or hollow glassware is attached during its manufacture. The iron rod is used for the so-called stapling of the glass . To do this, one end is dipped into liquid glass. The staple iron is placed under the bottom of the workpiece with a little hot glass mass to enable the muzzle to be worked out and fused together. This sticks to the staple iron. The glasses on which the stick is later broken off have the tack button on the bottom.
