Thicker and sturdier than gold leaf, this 23.5-karat yellow gold foil is easier to handle and is ideal for keum-boo, the centuries-old Korean art of gilding using heat and a burnisher to fuse very thin metal sheet to metal designs.
Each sheet is 23.5-karat (98% pure gold, 1.5% silver and 0.5% copper) and weighs approximately 7.8 grams.
• The small amount of copper in this foil poses no problems for enameling processes.
• The dimensions of this sheet will vary (sheets are approximately 3" to 3-1/2" square); thickness also will vary and is extremely difficult to measure precisely (sheets are approximately .000142" thick).
• IMPORTANT: As a supplier to the jewelry trade, Rio Grande strongly discourages any medical use of our fabrication metals. Your safety is important to us; therefore, we do not accept orders of fine gold for any purpose that includes ingesting, injecting, implanting or applying it topically.
