What was it made of?

The Mechanism is believed to be made of Bronze, or more specifically a low tin bronze (95% copper, 5% tin). However it is difficult to conceive how an accurate compositional analysis could be made considering the advanced state of corrosion the Mechanism exhibits. The frame-plate, all the gears, shafts, and fixings are made of bronze. The Mechanism was originally housed in a wooden box, which may not have been complete at the time of discovery. Once the mechanism was removed from the sea this soon disintegrated, and today only very few fragments of wood remain. It is not certain what type of wood was used.
