I just bought a clearance Yankee Candle tart warmer with a glass collecting pool There is no ceramic oven that the tealight goes in so the bottom of the tart doesn't get really hot. I had it going for about 30 mins and the tart barely melted. Afterwards I put the tart in my ceramic oil incense burner where the tealight is only 1" from the bottom of the tart bowl and it melted signifigantly faster where as you make the argument that the tart didn't melt at all in my my actual tart warmer that I got from Yankee candles with the 3" distance. Is this normal? am I just not being patient enough? Are these suppose to be a long steady 3-4 hour process? Because in my oil incense warmer the whole thing melted in 25-30 minutes. Thanks!
