i have been attempting candle making off an on for the past couple of years and I am stumpted about this. i am making pillars. The wax is 1343A, mold is 3 x3.5, 24 ply flt wick, 1/8 of uv, 1/2 tbs of vybar and 1 tbs to each color. I heated the wax to 190 then added the additived, the mold was warmed for the first color. I decreased the temp to 180 for the first pour and waited about 45 minutes. The mold was set in beans no water bath. After1 hour I poked relief holes by the wick waited until it solided up then poured the second color, poke relief holes after about an hour then filled. when i looked the next day i had a big sink hole on one side of the wick about 2 inches in width and about 2 inches in depth. I am wonder if adding more stearic will stop this sink hole. At first I thought it was because i did not warm the mold the first time so i melted it down and tryed again and the same thing happened. Any suggestions. I want the third time to be a charm and not get discouraged so I am waiting for a response before I continue. I enjoy making candles and would like to produce candles that can one day be sold so I must practice
