As the stove cooled down I could see tiny droplets of chemical being given off by the remaining cube. The latent heat was enough to have the cube continue to off-gas. I was holding the stove with a hot pad and was able to get a close look of the process. As it cooled further I could see the formation of tiny pointed crystals forming at the top edge of the tray and on the esbit itself. They looked really cool glistening in the sun light. After the remaining cube had cooled I lightly, very lightly, was able to scrape the tiny crystals off and put them on a sheet to photograph them for you to see. That's a lot of crystal chemical to be handling if you are saving the remaining tablet by touching it to put it into a ziplock bag. This is just a heads up infomercial on the use of esbit
Wherever you put the remaining piece it's sure to be losing some of those tiny crystals. It would be interesting to get some input from users on how they handle their stove and remaining esbit. My recent tests with the 4 gram tablets 2 at a time in the Esbitlyte burner show no signs of the crystal formation and residue left on the pot bottom.
After todays test we can see the amount of residue left after a 6 min. burn time.
