Our Pure Beeswax 12-15 hour Votive Candles are hand made at our farm in Michigan. The votives are made by pouring hot beeswax in special molds. We have making these candles for more than 30 years from our Honey and Candle Farm in Michigan. We have had questions about burn times of our 12-15 hr Votives. We test all of our candles for length of burn, quality of flame, smokiness and other factors. We do it the simple way by burning them and keeping a lot of notes. Beeswax Candles will burn longer and cleaner than all other waxes.WE SAW SOME SITES THAT HAD EXTREMELY LONG BURN TIMES ON TEALITE AND VOTIVES THAT WE DID NOT THINK WAS FACTUAL. Usually the burn time is based on two things, the amount of wax and the wick. There are many different wicks used for candles. We try to find the best ones for a consistent, clean, nice looking flame. If we wanted real long burn times we could use a smaller wick that would have a puny flame - it would burn longer but not be a nice, useful candle. We use pre-made wicks purchased from a major candle making supply warehouse.Our votives are 1 3/4 inch tall x 1 3/4 inch at top & 1 1/2 inch at base, weigh 1.9 oz and usually burn 12 to 15 hours.Votives must be burned in proper votive holder similar to size of votive. All beeswax should burn the same - the difference being in the wick that is used. Every candle will burn different - depending on slight variances on the amount of wax that is in it, how the wick is positioned (sometimes a wick at a slight angle may burn stronger and not last quite as long) , the container it is in, drafts when burning, etc.
