Fingerprints On A Candle

I was picking up my candle the other day and the scorch marks from the flame created charcoal dust on the glass container. when I pressed my finger into it it created a very detailed finger print I thought it looked very interesting because not everyday you see your fingerprints on house hold items although you always leave them, you never really see them, so I decided to photograph it and here are the results. what is also interesting is the sections of charcoal residue that is still left.
