Unlike out 2-Part Cone Mold, this is a flexible, one-piece mold. The Incense Dragon recommends you use any reversible mold by filling the empty cavities with your incense dough, pressing the outside of each cavity to eliminate gaps, and then placing the mold in your freezer. Depending on the ingredients you are using, in 10 - 30 minutes the cones will have frozen solid and can be removed by pressing on the tip of each cavity and pushing the frozen cone out of the mold. Once free of the mold, dry the incense just as you normally would.
You don’t have to use the freezer method. You can fill each cavity and then reverse the mold without freezing. You will almost certainly distort the shape of the cone, but if you set it down on its flat base, you can usually straighten the cone out fairly quickly. Which method to use just depends on what works best for you, but most of us find the freezer method the fastest and most consistent way to mold cones.
