Brass and Bronze

Now we will create Brass and Bronze, and yes they are different metals. Most people use the terms interchangeably but they are different metals, with different metallurgic properties and very different colors. Both are Copper alloys but are made up differently.

Brass has a lesser percentage of Copper with Zinc added and sometimes a few other metals as well. The mix results in a pale washed out gold coloration.

Bronze is at least 50% copper and sometimes more with the remainder made up of Tin and very rarely are any other metals mixed in. This mix results in a richer more copper reddish coloration.

There are a few other results of the different combinations of metals in Brass and Bronze but Ill get to that in the last section of this tutorial.

Brass

Most of the settings remain the same here as they did for Gold and Copper, the only things we are going to change are the colors in the main material. Click the colored box next to Diffuse and set the following values Red = 181, Green = 166, Blue = 66 and then click the Close button. Click and drag this color to the colored block in the First Specular Layer section and in the window that comes up click Copy to copy the color to this slot.

Now go down to the Second Specular Layer section and click the colored block. In the window that comes up set the following values Red = 214, Green = 214, Blue = 66 and click the Close button.

Apply the material to our Teapot, render, and behold the pretty, brass teapot.

Bronze

Click the colored block next to Diffuse and in the window that opens set the following values Red = 134, Green = 61, Blue = 42 and click the Close Button.

In the First Specular Layer section click the colored box and in the window that opens set the following values Red = 144, Green = 73, Blue = 41 and click the Close button.

In the Second Specular Layer section click the colored box and in the window that opens set the following values Red = 196, Green = 103, Blue = 46 and click the Close button.

Once again apply the material to the Teapot and render for a beautiful Bronze teapot.

Now onto Silver and Platinum
