Cola-Cola Plastic

 Melting Coca-Cola Caps

Cola-Cola caps are still amongst the best plastic to be used on my projects, the cherry red contrast has more accessible elements on a jewellery piece like the PlatAfrica bangle. I have provided some pictures to show how the cherry red plastic is achieved when melting Cola-Cola caps inside the oven kiln seen in figure 1.

If you melting plastic caps at the correct temperature at the oven kiln, you will see the printing of Cola-Cola in the plastic mold as seen in figure 2. Cola-Cola Caps are made of HDPE (High-Density Polyethylene). I have been testing plastic caps for months and I have found that coke bottle caps are melting at a great temperature of 200 to 231c. however, if the plastic is melted inside the mold as seen in figure 1, it does not get enough air to start to oxidize.
