I decided that to best describe my flooring feature in my presentation, I would create a material sample myself. I plan to create a concrete cube consisting of different colours of layered concrete to create the affect I desire. I coloured the concrete with concrete dyes. This week I began the process by making the cottle for the cube and starting with the first layer.

I made three cottles to allow room for error. I one fails, I still have two more I can fall back on.

Concrete Prior to Adding Water 
Dark Brown Concrete Dye 
Burnt Umber Oxide Concrete Dye
I used a combination of the two colours (above) to create a shift in colour from each layer.

I will be able to put the next layer of concrete in once this layer has dried enough.
