What is slab glass? Here is what the Benko Glass Company, where the glass in Joan's creation came from, has to say:
Dalle de Verre (Slab Glass)
"Dalle De Verre is a technique that was developed in Europe for use in early Christian churches. Originally colored chunks of glass were set into stone or clay. The panel medium was updated in the twentieth century with the use of concrete. Eventually in the 1950's epoxy resin was used because of its bonding capabilities and thermal expansion characteristics."
And I discovered that "slab" is a mighty word, with meanings far beyond glass bricks. We apply it to bacon, meat, cheese, concrete, stone, and wood. That at least is what I thought of until I checked it out on the Web. Slab can be an old car -- slow, low, and banging. But in Australia it is a case of beer. Other slang meanings I dare not repeat here. And last but not least there is the Sound and Literary Art Book from Slippery Rock University.
I salute the ABC Wednesday team for sending me sleuthing once more!
