Candle Snuffer:
To safely put out your candle.
First burn: Let the candle melt to the edge of the glass vessel (~2 hours), this will ensure your candle maintains a relatively flat surface, while preventing bumps or grooves.
Each time after: Trim wick (trimmers, scissors, nail clipper) to 1/4 inch between each use. To avoid oversized flames which lead to soot, try not to burn longer than 4 hours at a time.
