We burn a lot of candles, and when they are finished we're often left with part of the candle left, unburnt.
This could be some wax in a jar, or part of a pillar candle .
I've thought for some while that I could melt this wasted wax down and make some new candles.
Is this viable and would it be cost effective. What would I need to do this? Any recommendations would be welcome.
