Thanks, @kandlekrazy glad you are seeing the same thing--especially using the same base wax.
@TallTayl, in my mind, they don't look unsafe. I wouldn't feel good about selling them if they did--but always asking myself how to consistently improve.
I took a few pictures this afternoon. Some of these candles are not properly spaced, but know that these are all hand thrown ceramic jars, so heat/integrity of the canister hasn't been a factor.
@TallTayl, I know you use beeswax in your formulation. My hypothesis is adding beeswax would improve (higher melt point) flame height, while adding paraffin (lower melt point) would hinder flame height. I know there's other factors here, but wonder how large candle companies (besides millions of dollars in RD&E) optimize their flame height.
Thanks again for the responses--great discussion!
Best, DJ
