Hi I am interested in what is possible to achieve the highest quality surface finish for cast iron in the back yard. An obvious focus of attention is ceramic mold coatings. I have seen USA suppliers named on the forum with the caveat that they are often reluctant to sell in small quantities to a DIY foundry. In my case, there are no suppliers in-country and the cost of shipping is prohibitive. There are suppliers in China that do sell suitable ceramic powders in small quantities and reasonable shipping rates. I have not found ceramic mold coatings for cast iron. So the purpose of this thread is to identify a source of ceramic mold coating for the DIY cast iron foundry. It is very likely that the "source" will be a recipe of readily available materials to produce a DIY coating. The best source of information needed to identify a recipe is going to be from those who have the money and resources to undertake research that they are willing to publish. Specifically universities. So the first objective of this thread is to gather research papers on ceramic mold coatings. To kick things off, I have found and attached a research paper: Ceramic Coating for Cast House Application from the University of Belgrade, and Institute for Technology of Nuclear and Other Mineral Raw Materials.
