Right... that's is the new one I just got. It's very nice, it's light to hold and doesn't make a mess. The one that made a mess is the first one I got. I don't have a picture of that. I've used camphor, and have quite a few of the little tablets. But it does make a lot of smoke. I only use it occasionally, mostly for scenting up the house. Husband though I had an open jar of Vicks® VapoRub™.
I patterned mine from the nightly Mangala Aarti at temple. Given that there are people from all over, and it's a Vishnu temple, I'm not surprised. However, the Sri Venkateshwara aarti is more elaborate. I can't make out what the mantras are. But they use several deepas... one is the regular single puja deepa...
This one...
and one that looks like a brass jar, single flame at the top which makes a lot of smoke, may be camphor.
I have one of those too. It gets used for the minor aarati in the puja. The other one is just for final aarati.
