Thanks everyone! I guess what I am looking for is a jar that will hold 8oz of wax without looking too full or not full enough. I found a jar I liked on candlescience's site. If the wax weight (to fill line) is 5.8oz and the volume (to overflow) is 9.3 oz, does it mean that this is an ideal jar to hold 8oz of wax? I'm confused as to what the wax weight/volume means. I was going to call the company but they aren't open until Monday.
