Guess you could start with the mold in an empty water bath. I'd make more of a mess pouring the wax and then filling the bath with water. For a picture cane you need easy access to the inside of the mold to hold the picture to the side and the outside for the wet cloth and ice. I never use an icy water bath for my 'canes. Tepid water works best for me. Like anything with candles the key is the details. Temp of wax, preheating mold, heating pour pot and utensils, temp of water bath, etc. I use a length of chain on a Tupperware container and set it on top of my molds in the water bath to hold them in place. Any type of wt. set in any container, set on top of you mold will hold it in place in the water bath. My 'cane molds hold approx. 4 lb of wax. If that is a problem for you the hold a mold thingy might help. Just be sure it will work for your 'cane mold. Many won't handle a mold that big. Tip of the day: If you have cats, get the litter in the plastic pails. Makes a great water bath container. Also great for storing wax.
