THOSE OF YOU WHO LOVE TO BURN SCENTED WAX TARTS PLEASE BEWARE OF ALOT OF SELLERS OFFERING LOTS OF  TART BURNERS/WARMERS AND WHAT THEY ARE REALLY SELLING IS OIL BURNERS.  THERE IS A BIG DIFFERENCE BETWEEN A  TART BURNER/WARMER AND AN OIL BURNER.  NOTICE THE 2 BURNERS IN THE PICTURE ABOVE.  THE ONE ON THE LEFT WAS SOLD AS A TART WARMER & THAT'S WHAT IT IS.  THE ONE ON THE RIGHT WAS ALSO SOLD AS A TART WARMER BUT AS YOU CAN SEE....THERE'S NO WAY A STANDARD TART WOULD FIT ON THE TOP W/O OVERFLOWING!  THE ONE ON THE RIGHT IS AN OIL BURNER AND SHOULD NOT HAVE BEEN SOLD AS A TART WARMER .  THE WAX YOU SEE IN THE ONE ON THE RIGHT IS WHAT IS LEFT AFTER I PUT A STANDARD WAX TART IN IT AND NOT ONLY DID THE WAX OVERFLOW OUT OF THE TOP BUT THE WARMER WAS BURNING SOO HOT IT TURNED FROM OFF WHITE TO BROWN AS THE WARMER ITSELF BEGAN TO COOK. THE THROW SCENT OF THE TART USED IN THE OIL BURNER ON THE RIGHT WAS GONE WITHIN THE FIRST HOUR.    THE OIL BURNERS ARE  MUCH SMALLER, HOLD LESS LIQUID THAN A TART BURNER/WARMER & BURN VERY VERY HOT.  If  you use an OIL BURNER TO BURN TARTS....YOU WILL SOON NOTICE YOUR WAX TARTS SCENT THROW IS GONE AFTER ONE USE & EVEN BEFORE THE TEALIGHT IS EVEN FINISH, WHEREAS IF YOU HAD OF BURNED THAT PIECE OF WAX IN A TRUE TART BURNER/WARMER YOU COULD BURN THAT PIECE OF WAX MORE THAN ONE TIME.  THE FIRST TELL TELL SIGN YOU MAY BE GETTING AN OIL BURNER RATHER THAN A TART WARMER IS IF THE WARMER IS SMALL.  ANOTHER TELL TELL SIGN IS IF THE SELLER ADVERTISES THE BURNER FOR USE WITH OIL OR TARTS IN WHICH MOST CASES THEY ARE OIL BURNERS.  TWICE THIS WEEK I HAVE BEEN BURNED BY SELLERS OFFERING LOTS OF TART WARMERS ONLY TO GET THEM AND THEY ARE TINY OIL WARMERS THAT WILL NOT ACCEPT A STANDARD SIZE FLUTED WAX TART.  YES, THE OIL BURNERS MAY ACCEPT 1 OR 2 MINI WAX TARTS BUT EVEN STILL.....YOUR SCENT THROW WILL NOT LAST LONG BECAUSE OIL BURNERS BURN MUCH HOTTER THAN TART WARMERS.  I HAVE FOUND THIS FORM OF DECEPTION OF FALSE ADVERTISEMENT OF  TART WARMERS MAINLY WITH THE ONES POWERED BY TEALIGHTS.  YOU SHOULD BE AWARE OF SELLER THAT ADVERTISE "TART WARMER/OIL BURNER" BECAUSE WHILE A TRUE TART WARMER CAN BE USED TO WARM OIL....A OIL BURNER CAN NOT BE USED WITH WAX TARTS UNLESS THEY ARE MINI TARTS AND EVEN STILL YOUR SCENT THROW WILL BE GONE BEFORE THE TEALIGHT IS FINISH, SO I WOULD SUGGEST USING AN OIL WARMER JUST FOR OIL. ASK THE SELLER QUESTIONS ABOUT WHAT SIZE TART WILL THE BURNER HOLD BEFORE YOU PURCHASE A LOT FULL AND THEN HAVE  TO BUY OIL TO USE WITH THEM.   HOPE THIS HELPS :)
