Casting method
- 1. Model of baked clay
- 2. The lower half of the model is deposted in binder/Brussels earth.
- 3. The model is encased and the centre feed is produced.
- 4. Non-cohesive particles for loosening consisting of moulding sand and hardener. Centring points are also visible.
- 5. Filling the mould with silcer sand, which takes about a day to harden.
- 6. The moulding sand is rammed up.
- 7.The mould has been turned upside down, the front of the mould can now be seen. Again non-cohesive silver sand particles are added.
- 8. The mould is rammed up and smoothed.
- 9. After hardening the upper and lower mould are opened. The negative in the sand is now visible.
- 10.Upper and lower mould side by side,the model being on left.
- 11.Upper and lower mould with a fireproof coating and 6 mm wax layer. The wax layer indicates the thickness of the bronze.
- 12. Upper and lower mould,the core being in the lower mould. The runners and breather ducts are clearly visible.
- 13.Casting with high-grade bronze at 1200 degrees Celcius.
- 14.Having cooled down the mould is opened:the statue is born.The runners and breather ducts are clearly visible.
- 15.The runners and breather ducts have been ground off.The result:an accurate bronze casting of the model depicted in picture 1.After this casting is ground, polished and colour patined.
