For making a beautiful flower vase, at least 5 tools
are
rquired:
Blowpipes: a blowpipe is a hollow tube usually 48
to 52 long with a tapered end. It is made of mild steel about 5/8 OD with a
1/8 wall. The end is about7/8 OD, tapering back about 2 to the tube. The
blowpipe comes in all sizes, depending on the height of the worker and his
strength.
Pun ties: a punty is a solid rod for gathering
glass. It is used after the blowing is finished: the punty is attached to the
base of the piece so that neck or opening where the piece is broken off the
blowpipe, can be finished by reheating and shaping.
Yokes: The yoke is a Y-shaped support for the
blowpipe. In Sweden you can find Yoke with two steel balls in the corners of a
cast U-shape piece. The balls are set in a hole slightly larger than they are
so that they can roll freely on small ball bearings underneath. This yoke has
some advantages, but in the Eisch factory it was discarded foe a simple bent
rod welded onto an upright.
Benches: A simple bench, extended to the right for
right-handed people (this is one of those flagrant examples of prejudice
pointed out by the national Association for the Advancement of left-handed
People), has two arms extended forward to support a blowpipe as it is rolled
back and forth to work the glass form. A shield is customarily dropped from the
right side to protect the workers while making flower vase from the radiant
heat. The bench extension holds the jacks, shears, and other small tools. Water
buckets with the wood tools are customarily just behind this bench extension
but within reach of the outstretched hand of the seated worker.
Furnaces: and the final and most important tool for
making flower vase is furnace,
They are two types: pots and tanks. In a pot furnace the
glass is in a refractory container or clay pot; in the tank, the bottom of the
furnace itself holds the glass.
Making a furnace is not difficult, since all bricks are
standard sizes, the basic unit being 9x4 ½ x 2 ½, no mortar is required,
because the glass flows out the cracks and seal the furnace together as it
comes into the cooler parts of the wall.
Making simple flower vase is possible in this kind of
furnaces.
