I don't attempt to move my pot at all during use. I have a large Rowell Ladle and dip from the pot and fill my ingot moulds (set up on a sturdy table next to the smelter). After the melting pot is nearly empty, then I tilt it to load the ladle.
It is important to protect what the pot is sitting on. You WILL spill some molten metal from time to time. I set my smelter on a piece of plywood to keep the “junk” off the driveway. It is NOT easily removed...
I also have two layers of clothing (no synthetics - natural fibers ONLY as the synthetics will melt onto your skin as the molten metal sinks in). Can you spell “third degree burns"?
I have a dedicated set of clothes used for nothing else. Bib overalls with a shop apron over. It works quite well even in hot weather and yet the two layers are quite safe. Wear eye protection and a hat EVERY time. Remember, Murphy says, “If it can happen, it will". Pants legs over boots...
