Cast ingot. I made this one-pound (approximately) ingot by casting molten antimony into a graphite mold. When it was cooled to the point I could pick it up with a paper towel, I noticed a must unusual thing: The block was pinging like a bowl of Rice Crispies made out of silver bells. It went on for minutes and was really quite beautiful, much nicer than the tin or indium cries one reads about. I wonder if it's a coincidence that three elements in a row in the periodic table, indium, tin, and antimony, all cry when cooled or bent. I hope to record this antimony sound soon.
