The bowl photographed above took around 15 green bottle caps and 9 milk bottles to make, which still did not fill my mould - you always need more than you think! So prep a few more just in case.

 

HDPE plastics are safe to melt in a home oven as long as the room is kept well ventilated but a mini oven that is used outside is perfered, this is according to my own research so please do your own before beginning. 

 

I used -

• An oven

• A large amount of clean HPDE plastic (the plastic with a number '2' in the center of the recycling triangle on all plastic objects) 

• 2 metal bowls - 1 smaller than the other depending on the thickness you require

• A metal knife

• Tea towels 

(All items may be ruined or damaged so please use old items or items bought specifically for this project)

 

 

Making -

• Clean all your plastic or the residue will discolour your object

• Preheat the oven to 180 degrees 

• Cut up your plastic into small enough pieces to comfortably fit into your bowl 

• Place the plastic in the larger metal bowl in whatever layout you prefer, keeping it reasonably central.

• Place into the oven until all the plastic is melted (time varies with

• Scrape the excess plastic off the sides of the bowl so it's in one lump

• Place the smaller bowl on top and put back into the oven

• Wait for 5 - 10 minutes then remove from the oven

• Immediately place layers of teatowels over the bowls and press down firmly

• Let fully cool then remove the 2 bowls to reveal your bowl
