Torch Enameling with Opaque Enamels

Pro Tip: There are other ways to set up a torch station and you should use what works best for you. This is simply the way I like to torch fire.
Work on a fire-proof surface large enough that if a red-hot piece fell onto the work space it would land on this safe surface. Also consider the floor below your work surface. A hot piece may fall to the floor and you don't want it to ignite carpeting or anything else flammable. You WILL drop some pieces.

Place the fire brick on the fire-proof surface. Stand the brick on end so that it is tall.
The trivet will eventually go atop the fire brick.
Place the torch beside the fire brick on the side of your nondominant hand. For example, I am right-handed and my torch is on the left side of the brick (my nondominant hand side).
Put the tweezers on the dominant hand side of the brick.
The quench bowl (bowl of water) also goes on the dominant hand side but does not have to be on the fire-proof surface.
You also need a small area on either side of your station where you can sift enamel onto your piece.

Pro Tip: You are in charge of your own safety and the protection of your surroundings. While I am making suggestions herein, it's impossible to be sure I have mentioned all the common-sense measures that your situation requires.
Please consider that you are working with fire and fuel. I do not let children into my work area when I'm torching and suggest you free yourself of other distractions. Please don't answer the phone while your torch is flaming!
If you have filled your torch with fuel, put the fuel can under your torch station or far enough away that there's no chance it will come in contact with a flame. You do not want any paper or paper towels near the vicinity of the flame. Again, these are flammable.
Always wear safety glasses while using a torch.
Wear a mask while sifting enamel. Fines from the enamel escape into the air during sifting and although you can't see them, you will not want to inhale them. You may want to leave the mask on while using the torch as well.
Wear a protective apron. I wear a leather apron purchased at a welding store; however, for years I wore an old kitchen apron. A hot piece that falls on clothing will burn a hole.
If you have long hair, tie it back.
Please do not wear a garment with long loose sleeves that might find their way to the flame.
The quench bowl (bowl of water) is a safety guard. If you see an errant flame or detect some scorching, dump the water on the spot.
Be sure you have a working fire extinguisher available near the torching area.
