Another Technique Described by Shuman

from The Collector’s Encyclopedia of American Art Glass by John A. Shuman III

p. 31 – Steuben

Mica flakes varying in both size and density were used decoratively in some Steuben glass. The granular flakes were picked up from the marver on a gather of hot glass and covered with another layer before the object was shaped into the desired form. These examples made in the ’20s are rare; the color of the silver flecks varies with lighting and the tinted glass covering the mica. Footed vases and compotes were two shapes made in this manner.

from The Glass of Frederick Carder by Paul V. Gardner

p. 77 Mica-Flecked Decoration

This Technique was known long before Carder used it at Steuben. It consists of picking up pulverized mica flakes from the marver on the hot gather of glass and covering them with another layer of glass before the whole mass is worked into the desired form. The flakes varied in size and density of application,…. It will be noted that the silvery color of the mica flecks changes and assumes tints of the color of covering glass.
