The molybdenum disulfide powder arrived. I bought 50g of the cheapest I could find at 1-2um

It feels like super graphite between my fingers (you are not meant to get it on your fingers!).

The toxicity is apparently low but it is best to wear gloves and use it outside apparently.

Even at the 1-2um size (the largest powder I could see) it is so fine it seems to sublimate, like dry ice, into a gas or molybdenum smoke. I recommend the use of a mask.

I put a screwdriver tip scoop (<1g) of it into about 50grams of candle wax.
I thought it would make my handling my chain dirty, and the appearance of my chain is darker, but the wax traps the powder which did not come off on my hands.

My chain felt noticeably smoother, like a freshly cleaned and oiled chain at the very least.

I have also purchased a slow cooker so as not to damage the wax but it takes about 20 minutes on the high setting to melt the wax so I will probably keep using my standard electric cooker pot thing more often.
