Thank you both for your thoughts. This was just pure inexperience in candle making. When I started out I ordered several jars, the balmoral and the apothecary, because I thought they would make pretty candles. After deciding to go with the palm wax, I thought the jars just seem to fit the beauty of the wax. With the balmoral jar I started out with the rrd wicks. I have used rrd's 37,40,47,& 55. The rrd47 I have actually burned and got a pretty good burn, it didn't start to discolor until the very end and the sent really seemed to be off at this point. The other jar I made with the 47 I am on my 3rd test burn right now, and still have a lot of hang up on one side. There is no discoloration as of yet. When I made these jars, I used 1oz FO per lb of wax and a few snips of the color dye chips, they are not very dark. When trying to find new wicks, I bought some csn's and on the 4" I tried 2 csn 11's and went down to 2 csn 7's I am on my 2nd test burn on it and am happy with the way it is burning! Can you use dark colors with the Glass Glow without it clogging the wick or is this even a problem? I know this is lengthy, I'm sorry. If I can't make these work, I am going to be stuck with a whole case of these balmoral jars! Debbie
