Loss Prevention

  1. Safety glasses should always be worn in the metallography labs
  2. Gloves should always be worn when working with chemicals

Procedure

  1. Use an abrasive saw with a water-soluble oil as a lubricant to cut the sample to be mounted.
  2. Clean the sample using ethanol and dry with compressed air
  3. Grab the mold and place the sample into the mold. Make sure to place the surface to be examined face down.
  4. Grab the epoxy resin and corresponding hardener. Read the directions on the resin container for the proper mixture of resin-hardener. (fig. 1)
