CAVEMASTER DEMO PARTY
Amber is found washed up on beaches. The lumps range from reddish to orange to golden, and can be transparent, milky-translucent, or opaque. It is prized because it is pretty and can be carved with flint.
Star Carr artifact:
Amber has the odd property of attracting certain types of dust. It can raise fine fur. After being rubbed with hair, it is “charged” and can give off a spark, visible in the dark.
