Beach glass tumble

Here is a tumble of glass bits found on the beach, and bits I made from hundred plus year old bottles. All the old bottles were either broken, or had cracks in them, so value as old bottles. The red glass was a piece of fresnel lens from a ships running light I found on the beach. The red colour was produced using gold oxide. Anyhow, it was a large chunk that met the trim saw. The black lumps are from pieces of old black glass bottles....they are actually a greenish brown colour. OK...at least one of the black lumps is a piece of basalt from my driveway!
