The pit will burn actively for an hour or so.
Hence copper oxide phase may become visible under xrd after a high temperature sintering treatment which leads to diffusion and agglomeration of copper.
There are many things that will produce colors some better than others when placed in the pit.
This pit construction permits pockets of reduction within an overall oxidizing atmosphere.
Here is a non exclusive list of colorants for pit firing or to be used inside of a saggar.
