I agree with Tom Wirt and would state it differently, you can't patent
chemistry and only rarely biology. This is the reason that trade secrets
exist. The workings of the physical world are available to everyone and so
cannot be legally protected. It is only the special knowledge of combination
or process that companies protect, not the chemicals themselves.
In the case of glazes, the ingredients may be less important than the
processes of application and firing. You have the same constituents but don't
get the same results. You can see this with people using a glaze from the
same bucket and getting rather different results.
