Btw.. I found it at an abondoned mine north of Jonsondale bridge on the kern river
The diggings has it named "tungten occurance" but this stuff seems soft and tungsten is usually not found in metallic form. Any tests i could do?
A fairly simple chemical test for any tungsten ore is to grind to a fine powder and boil with hydrochloric acid for 15 minutes. If tungsten is present, the solution turns cloudy yellow.
I'm no expert but enjoy helping when I can... so some ideas:
1. Lead is soft, and you can buy test strips to detect lead paint. Presuming that these strips react with lead itself, and not a different component only found in lead paint, you could use one of these to figure out whether this is lead or not. The strips are available online or at most hardware stores.
2. Silver can be tested using an acid solution which is also available online.
That's about all I know, I'll leave it to the real experts to chime in further...
