Weird events in the last 4 days

So ive been workin on my wax blends for the blackened fire since i have to order the steric acid online. Found a additive that has it as a component but only extends burn time but 12-18 hours

Since saturday some of my candles of been burning down ridiculously fast. Had a 6x2inch pillar i made meltdown in 6 hours when a similar blend lasted 2-3 days, but the very next one i activated this morning was shorted lasted a good 13 hours with half the candle left.

Had to switch over to store bought 7 day candles for now to save on wax.

Wanted to share this in the event anyone else is has had any strange events happen.
