There are many nice and a whole lot more cheezy burners fro charcoal incense from import stores, and many people use Native American traditional Abalone shells. My solution is: I shop the many resale stores of Austin TX, and buy nice oversized cocktail or martini glasses, and then you can choose the ornamental gravel that goes into the glass to prevent the burning charcoal from cracking the glass. I've got black pebbles, mixed natural colored pebbles and silver-painted stone chips. Let me know if you have a preference. I will try to keep the photos up-to-date, but you might get something similar to the photo, because I'm buying them individually at resale shops. I really like this apparatus more than the import burners, because the long stem of the glass allows you to carry the incense about the house. 

Now you could accomplish this yourself with a trip to a used clothing store and a Joanns, but here I have done it for you already!
