Years ago I rescued some pieces of marble - it had been a garden ornament and looked like concrete but then... once it was broken the marble could be identified. At any rate it stayed at my place for a long time until I tackled it for a piece to go into the sculpture exhibition at Melbourne International Flower & Garden Show in 2025.
There are more pieces - I can do different things with different pieces - depending on where the fractures and bruising shows in the stone... always plenty to look forward to... next Summer when I'm happy to work with water feed tools and polishing blocks 😉
