Craqueleure is a painting term indicating shrinkage damage to the varnish. Sometimes also applied to crazing on ceramics. It could be that some used the term as a noun for glass finishes. On Monart this finishing style was named Cloisonne it was achieved by cracking the hot outer enamels by dipping into a bucket of water and then blowing some more to open out the cracks and reveal the underlying colour.
