Last Friday I burned Halo/Mars and it burned
completely black. So Monday I burned 4th pentacle of the moon and it looks like this. I've never had the label burn like this and the candle didn't start getting dark until about halfway through. The bottom is pretty clear. I'm not sure if it worked or if I need to do anything additional But one thing that is apparent is that "hoes mad".
Sometime just the candle burning will cause the glass to get black especially when it gets lower I wouldn't stress it, don't doubt it wait for movement then proceed
