Stevens and Williams


ca. 1900

Stevens and Williams Silveria is an embedded foil technique but not Burst Foil.

The invention of Silveria was due to John Northwood II, continuing the pioneering work of his father.  He developed Silveria in 1900.  Silveria glass is a colorful but abstract design in various physical shapes, made by sandwiching silver foil between two layers of glass.  The glass may be clear or colored or with trails of color.  Silveria is usually marked with “S&W” and “England”. 

John Northwood’s health began to fail in 1901.  Frederick Carder was then appointed chief designer for S&W.  This marked the end of what is known as Stevens and Williams “Fancy Period.”   John Northwood died in 1902 at the age of 65.

In regards to Burst Foil technique, Edward Webb and Joseph Webb both had produced their own versions in 1883, long before S&W’s Silveria in 1900.  Stevens and Williams' Silveria differed from Webb's foil work since the silver foil remained intact, rather than breaking into fragments.  Broken fragments of foil which are sandwiched between layers of glass are known as the “Burst Foil Technique”, not Silveria. 

There are many different types of embedded foil work of which Burst Foil is the most common and there are famous examples of it by Edward Webb’s 1883, “Oroide and Agrentine”.  He advertised the use of gold or silver foil between two layers of glass, respectively.  Arthur John Nash was responsible for both designs. 


Below are all  examples of real Stevens and Williams Silveria Glass.  Silveria glass is not plentiful and rose bowls are seldom seen, therefore most of the pieces below are vases not rose bowls.  However it is important to view the Silveria glass.  To see it is to know it. 


Below is a vase that is close to a rose bowl in a square shape with crimped .  It is 3" W x 2 3/4" T.
