Oil experiments


Here I experimented with melting plastic using vegetable oil ( same method used to melt chocolate) in a bowl submerged in boiling water.)  Got this idea from Thomas Thwaites 
toaster project book, where he used this method to make the plastic
 casing for his toaster.  



My new equipment ( 240 degree sugar thermometer, small saucepan) 



1st experiment : The silicone case flooded so let the plastic 
free in the oil. Going back to white as it cooled down



I used silicone cupcake holders from pound-land because silicone has a very 
high melting point (240 degrees)
Whereas HDPE, Polypropylene and polystyrene melt at around 130 degrees.


The plastic touching the casing is starting to melt


Quenching the whole mould in cool water to speed up the process.
