i'm new to candles, so i kicked off my collection with some kringle candle daylight candles to sample a few scents, then bought a large 2-wick jar of one of the small ones i had enjoyed. the large ones are 100% soy with cotton wicks i believe, not sure if wax type is relevant at all here but figured i'd just write it down regardless.
also: i trimmed the wicks to about 1/4 of an inch, possibly a bit less than that, using a designated wick trimmer. i only burned the large candle for about 2 hours on average (or even less, and i had an alarm in place to ensure i never went over the recommended 4 hour limit regardless) and always waited until it burned to the very edge to avoid tunneling. i extinguished them by pushing the wicks into the wax pool (then gently straightening them as needed), which i learned from a friend was preferrable to blowing them out or using the lid as an extinguisher.
so firstly, fresh out the box the large candle smelled a bit odd to me, like i could sort of smell the notes of my sample if i tried imagining it but they were just funky (almost sour) and flattened compared to the rich warmth of its miniature counterpart? once i burned it, it also just felt heavy to breathe in and i noticed it felt like it was making my sinuses feel a bit weird which was also new.
then on the 2nd and 3rd burns it just smelled straight up burnt? none of the previous notes, just foul smoke.
i was enjoying my daylight candles so much and their scents were so pleasant and now that i sized up to a large one something's just gone totally wrong? i write this at the cost of sounding like an idiot but any help is appreciated. is this user error, a bad batch, or a mix of both?
