I melt my wax on warm on my presto which is around 175-180. I measure out 14 oz of melted wax and then add my color. I usecolor crystals from makescents and I have also tried little slivers of color from a color block. Once the color is blended, I add my oil (tried 1 oz up to 1.5 oz)and stir for 3 -5 minutes. I let it sit til it cools to a tomato juice consistency mix again then pour. I have even tried to wait til the wax cooled a little before I added the oil (around 140 - 150). I have tried 8 oz jelly jars, mason jars and 8 oz wide mouth jars. I have used cd 10, 12 and 14 on the 8 oz jelly jars, HTP 105 and CD 16 on my 8 oz wide mouth, HTP 105 and CD 16 on mason jars. I have fragrances from KY candle, natures garden, ICS, candle source and alabaster. I don't have a problem with my melt pool, I can get the 8 oz wide mouth to burn clean with cd 16 and my jelly jars with the cd 12 or 14 depending on the oil. The fruity fragrances are what I can't get to throw in a candle. I have banana nut bread, caramel praline and creme brulee that I don't think anyone can mess up, it throws no matter what the combination lol All of my tarts throw well there is just something about the candles that the fruit fragrances don't want to throw in. I poured some yesterday to test RRD wicks. I am sure I am leaving something out but this is the somewhat quick run down of what I have tried.
