Hi everyone, I'm an absolute newbie in candle making. In fact, I purchased the ingredients and a mold yesterday and made my first candle. After about and hour of filling the mold, you could already see a cavity forming in the center of the candle. When the candle was cold, the cavity had about 1 to 1 and a half inches of depth. I had used 25 grams of stearic acid and 8 ounces of parafin wax. I also used a little dye, but no fragance (I forgot to put it in because I was too excited). I'm letting my second candle cool off right now, but it was already showing the same behaviour. This time I used 9 ounces of parafin wax and the same amount of stearic acid. I left a little molten wax to "refill" the cavity but then a lot of bubbles appeared. I guess the molten wax was not hot enough. I'd like to know if there's a definitive way of avoiding this cavity from forming. My wife even suggested using the candle upside down, which seems reasonable, but I hope there's a better solution. I appreciate your help. Mauricio
