Definition of sandiver in English:



  • A scum that forms on molten glass.

    • ‘If a small quantity, even a pint of water were to be thrown into a crucible of glass in a melted or rather a melting state, while the scum or sandiver is upon its surface, the water would be converted instantly into steam so that an explosion would take place; and if the quantity of water were more considerable, the furnace would be blown down.’


Late Middle English: apparently from Old French suin de verre exudation from glass from suer to sweat + verre glass.
