It is the 12 oz Status Jar.. 3" Diameter.. They say CD 14 is for 3.5" to 4" but I find my 70/30 blend needs larger than a CD 10.. At first I had my FO at 10% but kicked it down to 7% and I find it burning much smoother.. Even at 14, some of my heavy scents leave hangup on a regular 4 hour burn.. You ever work with the Green Leaf 70/30 blend back when they were in business?? I thought I would ask if you ever tested with it even though I know you are a C3 lover
