So, I created my first two jar candles. Used 1lb (16oz) of wax and filled the first container to the bottom of the neck, which appears to be the 6-7oz mark. Apparently not. Started to fill the second one and got about 3/4 of the way full and ran out of wax. So apparently 8+8 doesnt equal 16 anymore. But hey, it was my very first time ever pouring a jar. I consider it a success that a) didn't burn the house down, didn't burn myself, c) didn't spill anything, and d) i'm trying something new since I have the tart/melt business down to a science!
