A few years ago, I forwarded to The E-Sylum an article from MIT's Technology Review about students each year casting bronze medals. While attending my 40th MIT reunion this weekend,I stumbled onto a display related to this program. These heavy, uniface "medallions", perhaps 2 ½" in diameter, are made using the lost wax process by students in the Department of Material Scienceand Engineering (DMSE, or Course III in MIT-speak) for the current year's graduates, as a graduation memento. In addition to examples of unfinished and finished pieces, and a brief description, thedisplay had a running 3-minute video showing the entire process, which you can watch on YouTube. Parenthetically, Eric Newman is also an MIT grad, Class of '32, so this was his 85th reunion year!
