Fig. no shows a the first heating. When the piece is sufficiently cool to handle, 2JO MECHANICAL DENTISTRY. a second application of body is made for the purpose of repairingany defects that may have occurred in the baking; this done, thepiece is again introduced as before into the upper muffle, then intothe lower, allowing the second bake to become a little harder thanthe first, but not so much as to appear glossy.
