Keum-boo Gold for Jewelry with Hanna-Katarina and Brienna Hall

Keum-boo (Korean: 금부; also Geumbu, Kum-Boo or Kum-bu—Korean "attached gold") is an ancient Korean Gilding technique used to apply thin sheets of gold to silver.Traditionally, this technique is accomplished by first depleting a surface of stealing silver to bring up a thin layer of fine silver to the surface. Then 24 carat gold foil is applied with heat and pressure—to produce a permanent diffusion bond.

In this workshop you will learn all the basics of this beautiful surface technique and how to: depletion guild, how to design with intention, cut and apply the gold foil to three dimensional, flat, and textured metal surfaces, techniques for finishing. Together you investigate the various ways metal surfaces, particularly fine silver, can be enhanced by manipulation..through the application of gold foil, to a prepared silver surface.

Topics covered:

• Depletion gilding or ‘silvering’ the metal surface in preparation.
• Design with intention -Cutting gold foil
• Adhesion of gold foil to the silver surface by means of heat and pressure
• The decorative potential of the gold fusion process
• Use of the rolling mill to add texture to the metal - Fusion and soldering of findings to the surface

About Brienna Hall
Brienna holds a bachelor’s degree in sculpture with a minor in fiber arts from the Kansas City Art Institute. Her artistic journey began as a photographer and milliner, where she honed her skills in crafting exquisite headwear and creating ornate, dreamlike imagery. This creative foundation eventually led her to establish Shrine Jewelry, a line that lovingly merges her love for adornment with the artistry of fine metalwork. Working from her studio in Mendocino, California, Brienna brings her unique vision to life, drawing inspiration from the rugged beauty of the Northern California coast and the mystic worlds around us. In addition to her work as a jewelry artist, Brienna continues to study photography and teaches workshops on the ancient technique of sand casting precious metals, sharing her expertise throughout Northern California. Starting in 2025, she is expanding these workshops to the Midwest and Italy. Her philosophy as a jeweler is rooted in the belief that our bodies are sacred shrines deserving of adornment. Each piece of jewelry is crafted to honor this intimate space, blending organic shapes, repetitive patterns, and textile-inspired techniques with the process of metalsmithing. Through sand casting, fabrication, keum-boo and textile techniques Brienna creates one-of-a-kind works, each imbued with a sense of individuality and timelessness.
