Fire safety is important
Read better fire safety stuff. I literally re-wrote the entire post in my grimoire because i knew that my candles were secure.
Main problem arrived when i was eating, and i realized in that moment, that one candle was dressed time ago in a multi-pre-spell-candle.
I think i created a strong spell, so strong that one candle changed colour from green to white (akasha).
Anyway, main problem was pine rosin inside the candle. I totally forgot that, and the high temperature for long time in lower space of candle created that.
FIRE SECURITY PART:
Use a base with sand to avoid burning and follow candles step by step. Is better, trust me
Instead of that, you can use a stone if can hold strong heat (600-800°C)
IMPORTANT: beeswax in high temperature, start to burn completely. To avoid that, remember to cut the wick near the base of the candle
Geez! Watch out! I like to do multi-spells instead of a single one, because for me works better like this. Anyway...fortuna major ;)
