It can take anywhere from one day to a week to hand carve a wax pattern that becomes the prototype for a cast design. All of our prototypes are originally sculpted in special carving wax by Balinese artisans that have years of carving experience. In order to do this the design must be castable and we need at least one of the following per design to give our artisan:

1) A sample that can be copied to make a prototype or an exact sized sketch from all views.
2) Detailed sketches of the design from front, top and side views with dimensions in millimeters.
3) Clear pictures from at least two different views and dimensions in millimeters.

View our designers official website www.madesandiago.com for some ideas how to do this if you need custom production in medium to large quantities.

After carving is complete, the wax prototype has a wax wire attached (known as a sprue) and is then cast to change the wax prototype into a silver prototype. See our casting process here.

At last we have the silver prototype or “master”. The master needs to be sanded, and touched up and may need adjustment for size etc.

We need a minimum of 6 days for a normal sketched design to become a silver prototype.
