Challenging 'intuition' in ascending casting method:

One expects the bronze to nicely travel down the casting channel and then rise in the statue making use of each gate consecutively.

This simulation shows how higher gates 'do not take...

In 1960 Amsterdam asked Cor Hund, accomplished artist and director of the Rijksacademy, to create a monument in memory of the writer Multatuli.

Ten years later, although he made nearly 150 sculptures for the monument, he gives the assignment back.

This is the s...

To each colour a property

Hardly no deformation,discovering this blue wax was real relief! Hardly no deformation, we could cast solid foundry models. The problem could be if correction is needed, this wax is hard and brittle.

1. ALLOY

The quantity and kind of alloying elements of the bronze have influence on the color of the metal and on the colors that develop when under influence from chemicals. 

The most common alloys used in art casting are silicon, tin and lead bronze.

The...

The 'as cast' skin of silicon bronze is rather dull if the casting is done properly, metal poured warm, mold free enough from carbon. The skin is grey/black is little bit powdery with some remnants of the casting mold attached. The black layer is black copper oxide whi...

The patina is a coloured layer on the bronze. This coloured layer can be the result of the casting process, artificially made or developed in time in an environment which makes chemical actions possible.

The patina can be used to enhance the appearance of the...

The color of the flame coming from the melting furnace should be slightly green. The green color is emitted by the burning copper vapor which escapes from the melt bath. Every metal burns with a specific color, copper green and is the most dominant metal in the alloy....
