Copper matte converting is an important process in copper pyro-metallurgy, involving chemical reactions, fluid flow and transformation of both heat and mass.

We will make use of a variety of techniques to get to usable mattes, work with solids & adjustment layers and even dip into the 3d-space for some advanced relighting.

The lightweight coverage instantly perfects skin and leaves a beautiful, matte finish.

In the same time, the effect of technological condition, such as temperature, volume and pressure of air, on the sticking matte-kiln-crust was also examined.

The preparation and application of internal and external sulfonium cationic polymer since 1960s are summarized comprehensively in this paper.
