I checked around on the internet and found several sites where others have been doing the same thing. The best part was that everything I'd need were pretty common household items. So, I rounded up the necessary supplies and began imagining how great life would be once I'd cornered the international diamond market.
Step 1: Materials
A standard home microwave oven
2 coffee mugs
3 pieces of 3mm graphite pencil lead
A few drops of extra virgin olive oil
A 5" piece of 100% cotton thread
The hardest item to find was the 100% cotton thread. It's amazing how scarce that stuff is. After searching through all of our sewing notions, I finally found some black thread that I think my mom bought back in the 70's.
Step 2: Prepare the Olive Oil
Place a few drops of olive oil onto a plate and lay the thread in the oil. The thread will absorb some of the oil.
