Cast aluminium medallions of Pinkie Pie and Rarity
Made in a home made crucible constructed out of a grill starter and an old vacuum-cleaner that was cut in half.
The crucible was an emptied fire extinguisher.
Aluminium is mainly old CPU cooling blocks.
Mold is based on a beer glass and a can combined with a mc donalds pony.
Heres a link to some videos of the process
