Equipment or Bill of Materials[edit]

  1. safety glasses
  2. Thermolyne hot plate
  3. metal knife/spatula
  4. 150x75 mm pyrex glass container
  5. watchglass (6 in. diameter)
  6. heat resistant work gloves
  7. dust mask (when using glass)
  8. K-type thermocouple & reader
  9. polypropylene granulated from wood chipper
  10. glass powder
  11. timer of some sort

Calibration & Tolerances[edit]

Operation & Procedure[edit]

  1. turn on hot plate to 5 for heat setting.
  2. place glass container on hot plate with thermocouple touching bottom of container and watchglass on top, facing downward as lid.
  3. when thermocouple reads 160 deg Celsius, add polypropylene (PP) and glass powder
  • if the PP and glass are added at the same time and heated together, an oxidation reaction will likely occur
  1. for record-keeping purposes, time how long it takes to melt the plastic/composite.


  1. trun off hot plate and let it cool down
  2. also allow composite to cool down after use
