Reifschlager Gallery At The Rockwell Museum–pre 2000

The Intarsia glass made at Steuben in the late 1920s and early 1930s was considered by Carder to be his greatest achievement in artistic glassmaking.

The Intarsia pieces made about 1930 usually range from about one-sixteenth to one-eighth inch in thickness and are reality three layers of glass: two colorless crystal glass layers encasing a layer of colored glass that forms the ornamental design.

All Intarsia pieces sold were signed with a facsimile signature, “Fred’k Carder,” engraved on the lower side of the bowl above the foot or stem, non on the underside of the foot as in the case of Aurene and other pieces.
