YALEY-Glass Fill Candle Wax. 1 1/2 pound block. This wax has a higher oil content than the premium wax. It is used extensively for candles that are burned in glass containers. Drinking glasses, goblets, brandy snifters and rose bowls make beautiful holders for candles. This glass fill wax will leave no residue on the glass as it burns and will not shrink away from the sides of the container.
