HOT CAST BRONZE
The more extensive method also known as the lost wax method. A hollow wax image is made then coated with a thick ceramic coating, dried then the wax is burnt away, leaving a ceramic mould. The molten Bronze is then poured into the ceramic mould.
After cooling the ceramic is chipped away. The finished Bronze is then cleaned with chemicals, polished and waxed to finish.
This explains the difference in quality and its cost.
Keep your Bronze looking new by dusting, waxing and polish yearly.
This method was widely used up until ceramic became more popular as it was easy and cheaper to make and if broken could be easily replaced.
