The story of collection
I was driving along High Street and spotted this skip bin, just 1.3km away from my home-garage-studio. The skip bin was located in a parking bay outside of a commercial property that was being renovated in late 2023.

Appearance
Grey, coarse and gritty with aggregate of dark brown and charcoal coloured rock within. Rocks are smooth. Some faces are smooth or polished (ground floor application).
Characteristics & Crushing Notes
Grey cement easily crushable and crumbly after bisque firing. Aggregate is dense and loud to shatter. Breakdown and separate different components for greater versatility, control and wider range of results.
Post-firing Characteristics (Cone 6)
Lime popouts occur. Some iron-rich rocks melt. Depending on particle size, variation in colours from green to orange to brown.
