......martha stewart really needs to stop with these non descriptive candle tutorials. Candle making isnt just "stick wick in wax, add scent" Some fragrances are incredibly flamable... "lemon oil" could mean many things, and a dried lemon peel sounds flamable to me as well.
I've been making candles for 25 years and here are my tips if someone wants these to actually burn properly.
#1. you need a wick appropriate to the container size and wax viscosity. Beeswax requires a larger wick than paraffin, slightly larger than soy. Measure each lemon, refer to a candle wick size chart, which still wont be 100% proper, and go from there. You wont be able to find appropriate wicks at your local craft store, so that means ordering some. I would suggest HTP wicks for this purpose. Wick up from what it suggests, because beeswax requires the largest size recommended, sometimes larger.
#2. "Lemon oil" would be either lemon essential oil or lemon fragrance oil (make sure its rated for candle use, aka the flashpoint is appropriate) it just so happens lemon essential oil flashpoint is below the flashpoint needed to create scent (maybe faint but not noticeable) in a candle. Higher flashpoint= more fragrance. Lemon essential oil wont create a great smelling candle. it just wont. Especially not in beeswax which naturally has a strong odor of its own. Not to mention 1/2 tsp in 1 pound of wax is laughable. One ounce fragrance per pound is pretty standard.
#3. Seriously? Most candle makers spend years learning the properties of fragrances, eaxes, containers, wicks... so its just laughable to me (and many others) to read "stick wick in wax. add scent. light. burn."

ok, //end rant//...

thanks for schooling us SilverFirsFarm ! :)

Another candle maker (novice - only been at it for a year) chiming in to say that the instructions provided are way over-simplified.
Thanks SilverFirsFarm for all the pertinent info!

Thanks SilverFirsFarm! Now do you know if it's true that soy and beeswax are cleaner than paraffin? I've been hearing that paraffin releases toxins in the air similar to what's found in diesel exhaust.

Beeswax is the ultimate clean! Really, how clean a candle burns comes down to the wick and the fragrance. If a wick isnt kept trimmed, its going to make a carbon ball.. and that carbon ball will put off smoke. So really, a well wicked paraffin candle can be much cleaner than a soy, or beeswax... just as long as its wicked well.
Theres alot of debate on the soy/paraffin and I really have to say I'm biased (since I use soy) but I've read alot of research that says paraffin is perfectly safe.
The only 100% natural waxes, in my opinion, are bayberry (really cool!) and beeswax... even soy wax, while made from a totally renewable and natural thing- is put through alot of chemical process to become wax.
In the end I think it comes down to who you believe... this is a pretty good article :)

Won't these grow mold?

Wow SilverFirsFarm that was interesting info.

Actually I like it when someone takes the air out of Martha's sails. Thanks SilverFirsFarm

These are really cute, but I hope everyone reads SilverFirsFarm's comment. Making candles requires a certain amount of education for safety and not even the brick & mortar sellers get it right. I once had a Bath & Bodyworks candle explode due to air pockets and send hot wax all over the curtains. Not good.
