I've been doing this for years. I found that you need a very fine strainer to strain out the sooty particles. I also add some candle scent from the craft store.
I prefer the jar type candle for safety and aesthetic reasons. Any old container works fine as long as it has straight sides
great 'ible, though i personally would be cautious about doing this in a microwave. there is always the possibility that, because microwaves often have a tendency to cook unevenly, that the wax could melt in layers, form bubbles, and explode. as to the likelihood of that actually happening, i have no idea. it may not happen at all, but i'm going to be very careful about this.

Congrats on your first Instructable. Does the glass get hot when microwaved?

Great work, using a microwave is a good idea. One warning though, when we tried this the resulting candle gave off alot of blacker smoke, which actually stained the wall and ceiling.

I noticed more soot also, but just keep your wick short it will not be too much of a problem, I burned my candle inside my apartment and it didn't stain the white walls or ceiling.
