The silver heart was made by coating the Rapid Prototype with a thin layer of copper. This was then coated in silver. Silver appear pure white in colour until it is polished or abraded. I have left some recesses as unpolished silver (white) to emphasise the three dimensionality of the object.

The golden heart is an anatomically accurate heart, scaled down to fit in the palm of your hand. The Rapid Prototype is covered in gold leaf.
