Slag glass is the term given to decorative pressed glass that has been given an opaque look with streaks running through it to give it a marbled appearance. The use of slag glass is extremely effective in creating a decorative finish and when applied to a table lamp shade it is particularly effective thanks to the way the light plays off the various shades and highlights.
The manufacture of slag glass originated in the 19th century and involved the process of adding slag from iron-smelting works to molten glass. The results were the creation of richly marbled patterned glass that became extremely popular with collectors and the general population of homemakers.
It is hardly surprising that slag glass table lamps have become extremely popular with designers and decorators because they are a simple way of introducing texture and color to a room.
Below is a selection of table lamps featuring slag glass lamp shades in a variety of different shapes and sizes. Among the lamps you will find here include many that were made during the Art Nouveau era including a selection of Tiffany lamps.

It is not uncommon today for dealers to refer to any lamp shade made from glass featuring the odd streak or pattern as a slag glass lamp shade. This is where the buyer should look more closely and inspect the quality of the shade themselves. A lamp that contains a shade made from true slag glass may be determined by checking the pressed glass closely to discover how thoroughly the streaking and marbling has been effected.
