I think having a lid or not will mostly be personal preference. I happen to like lids on my jar candles because they keep dust out when I'm not burning them and I use the lid to snuff the flame. They're also easier to package up when giving as gifts. I think the lid helps keep the scent from fading too.
I always bought jar candles with lids for the reasons that you mentioned. I had a difficult time finding containers that I liked. I ordered some squat apothecary jars with bubble lids that looked promising. When they arrived, the dimensions were not as stated on the website which meant that they were 1/4" too tall to fit on shelves where I intended to store them
Beyond that, the glass was extremely thin/lightweight (probably why shipping was so reasonable) and the seal cheap plastic rather than rubber or silicone. (They are now posted on Craigslist in the hopes that I can recoup my money without paying for return shipping.)
I found some containers that I really love, but they do not have lids and am trying to figure out if this is a deal breaker. I burn candles regularly enough that dust is not a major issue and I am happy to blow out a wick. Fragrance loss is my primary concern.
It makes sense to me that cold throw would dissipate without an airtight seal, but it seems counter-intuitive that hot throw would be affected. Am I wrong?

What Krista said, and also...
Everyone is surprised at the testing time and materials needed to design one type of candle in one fragrance so that it's safe, burns down well and throws scent. Do yourself a bigger favor than you can imagine and choose whichever container is easier to wick. Generally speaking, a smaller diameter and a less odd shape is easier. Get an assortment of wicks, meaning a range of sizes and preferably more than one type.
Thanks for the heads up. I was aware that testing would be required but am hoping that I did not underestimate how much. Thanks for the fair warning.
Since these are candles for my personal use, I am inclined to get containers that I love and figure out how to make them work. The ones that I am eyeballing are regular cylinders (no odd shapes), but larger in diameter (4"). I hoped that the larger size would limit the wicks available to try.
If all else fails, I am assuming that I can simply reduce the wick size and use three to get an even burn pool.:think:
