DEPLETION GILDING
Charles Lewton-Brain, 20pp, 1990
Describes the approaches that goldsmiths have used historically in
various cultures to remove base metals from gold alloys for refining
or “coloring gold:” depletion gilding. Contains an extensive listing of
recipes from many historical and contemporary sources designed
to foster contrast and comparison and deepen understanding of the
subject. This paper is intended for only and is not a “how
to” for depletion gilding. Looseleaf bound - 13oz. - 0204209 - $15.50
FORMING USING METAL CHARACTERISTICS
Charles Lewton-Brain, 45pp, 1985/90
Fold forming is a system of sheet metal forming that emphasizes
forming using the metal’s characteristics. Forms are derived from
the natural plasticity, ductility and elasticity of the metal. The system
is internationally recognized as a new approach to working metal
that is extremely efficient and rapid. Tools include fingers, hands,
hammers, mallets, anvil and rolling mills. The paper has a theoretical
introduction and step-by-step recipes for quickly working sheet metal.

GOLD AND SILVER SURFACE APPLICATIONS UNDER ENAMEL
Charles Lewton-Brain, 18pp, 1988/93
Offers several methods that can be used for applying gold and silver
to copper and other metals. The new surface then can be enamelled
over, providing the enamelist with a new pallette of effects and a new
vocabulary of surface design. Looseleaf bound - 12oz. - 0204208 - $15.50
GOLD SURFACE APPLICATIONS
Charles Lewton-Brain, 27pp, 1985
A technological review that discusses results of a research project for
the Society of North American Goldsmiths. It describes fusion applications
(gold painting), doublee, depletion gilding (tumbaga, guanin), inlay and
overlay procedures and has a discussion of fire gilding. Control factors
for free compositional choice are defined and demonstrated.
