A friend got some of our tealights a week or so ago and tested them out. Here is what he said:
"I picked up some beeswax tea lights from you at the Capitol Hill farmer's market (Seattle), and you asked me to let you know how long the burned.
I was burning two of them for 170 minutes, before I blew them out. I can't be sure, but I'd guess there is another hour left in them.
There was one surprise though, which is that they generate a lot of smoke. I wasn't noticing, but them my wife came home, and she couldn't believe how smokey it was in the house. So you may want to work on that part of it. I hope it helps!"
What causes the smokey burn?
