Very excellent, very excellent, my friend, I enjoyed the idea that you are practical and can help a lot in the test and standard. You use very good ideas for testing gold. I am sure that you will provide interesting solutions in Fire Assay method. For example, similar to Indonesia, where they extract copper and gold with coal furnaces. Thank you very much and I wish you always deserve the best.
Thanks, teacher!
