Simulating Reflectance at Interfaces Coated with Household Paints

The paint and coatings industry is constantly working to improve their product, making a more efficient product at a cheaper cost. This requires some research and learning on the part of the companies, particularly in optical studies. For example, Burgess Pigment Company has developed a method, using a flash calciner, to quickly dehydrate clay, essentially popping it like popcorn, in order to add air pockets to the individual particles of clay. Clay that has undergone this process can improve the reflective properties of paint. The human eye, as a sensory organ, relies on reflected light in order to provide vision. As the major goal of paint is to be seen, it is easy to infer that it would be of utmost importance for the paint to reflect large amounts of light to appear more visible to the human eye and so using clay that has air pockets would be more desirable. The primary goal of this thesis will be to explore optical theory in an attempt to explain why the addition of air pockets could produce a more effective product.
