This is my first test batch. 1) your wax(es) choice and whether is it a pillar wax or container wax - EcoSoya PB, pillar wax 2) your fragrance load - 6.25% 3) the type of warmer that works best for you and the wattage of the light bulb if applicable - using a Scentsy light bulb warmer with a 25W bulb 4) your result - I put it in the warmer this morning, and one of my tarts is the same by weight as two Scentsy cubes (what's recommended for use in this size of warmer). The tart melted completely in short order, about 10-15 minutes, but the throw wasn't terribly strong. I had two going, one in our living room, which is a fairly open space, and one in our bathroom, which is a pretty small space, and I didn't get great throw in either. I'll try upping the fragrance load, and if that doesn't help, I'll check out a different wax. The tarts are recently made. I'll also retest one in a few days, see if some curing time makes a difference.
