For all those considering or already doing enameling, please take heed. Wear a respirator, and not just any particulate dusk mask. One rated NS-97 or above.
Enamel is ground glass. Yes, ground glass! That means all those tiny “dust” particles are sharp and if they get into your lungs you are in trouble. Most enameling classes do not emphasize this strongly enough. In fact, many instructors don’t require students to wear masks and they don’t wear masks. WEAR A MASK!
Also, when cleaning up, use a wet disposable towel, even for mopping up the floor.
The above pictured respirator is available at Home Depot for about $25. If you find a better deal, let me know. Click the image to link to the page on Home Depot.
