Dear all,
I want to analyze slag samples to obtain information about the ores smelted, the technology of smelt, and the required temperatures and atmosphere conditions. However, I am not sure about the best way to prepare and analyze the samples I recovered from the site I am studying. It consists of four spanish colonials reverberatory furnaces and I took some samples of slag to analyze. According to geological reports, some previous analysis and historical references, the furnaces could have smelt silver and lead.
I have already cut the samples of slag, mounted them in epoxy resin and polish its surfaces, using standard procedures for metallographic studies. However, as I plan to analyze the samples with SEM/EDX, I am not sure if I should attack the surfaces chemically to reveal its structure or not (as it is done with metal samples). I should attack slag samples or I should analyze them polished only?
I have observed the polished surfaces with a metallographic microscope and in most cases, there is a quite uniform surface with some bright inclusions, some oxides and tubular grey shapes. I haven't observed it with cross-polarized light yet, but I will do it to see if I can identify some other phases.
Thank you very much for your help.
