Glass golems are the result of polypiling too many worthless pieces of glass. They drop worthless pieces of glass when killed. As a result, some players, for their gem-hoarding needs, like to generate glass golems to identify more worthless pieces of glass.
"The original story harks back, so they say, to the sixteenth
century. Using long-lost formulas from the Kabbala, a rabbi is
said to have made an artificial man -- the so-called Golem -- to
help ring the bells in the Synagogue and for all kinds of other
"But he hadn't made a full man, and it was animated by some sort
of vegetable half-life. What life it had, too, so the story
runs, was only derived from the magic charm placed behind its
teeth each day, that drew down to itself what was known as the
`free sidereal strength of the universe.'
"One evening, before evening prayers, the rabbi forgot to take
the charm out of the Golem's mouth, and it fell into a frenzy.
It raged through the dark streets, smashing everything in its
path, until the rabbi caught up with it, removed the charm, and
destroyed it. Then the Golem collapsed, lifeless. All that was
left of it was a small clay image, which you can still see in
the Old Synagogue." ...
