A geologic field test was modified for determining the presence of gold in dental alloys. This qualitative test gave positive evidence for the presence of gold in most of the alloy samples tested containing 59% or more gold. It is recommended that dentists use this procedure for color comparison of castings to alloy ingot samples of known composition. More definitive professional assaying may be desired for confirmation.
为确定牙科合金中是否存在金，对一项地质现场测试进行了改进。这项定性测试为大多数测试的含金59%或更多的合金样品中存在金提供了阳性证据。建议牙医使用此程序对铸件与已知成分的合金铸锭样品进行颜色比较。如需确认，可能需要更权威的专业分析。
