PSA: My new habit of marking heat zones with soapstone changed my forge work

I used to just eyeball where to heat the steel, which often led to cold shuts or uneven bends. So last month, I started using a soapstone marker to draw lines on the metal before putting it in the forge. I mark the spots that need the most heat and where to avoid overheating. This simple step has made my bends cleaner and reduced the number of times I have to reheat a piece. But I'm still figuring out the best way to do it for different shapes, like scrolls or twists. Do any of you use something similar, or have other tricks for marking metal? Also, does soapstone wash off easily after, or do you have a better marker idea? I'd appreciate any pointers from folks who've tried this.

Soapstone marker" seems like extra work. Just heat it more evenly.

For intricate plasma cutting, heating evenly doesn't help with the guide lines. Soapstone marks SURVIVE the initial heat and let you focus on the cut. Without it, you can lose your place and ruin the piece. I've seen guys try to just heat evenly and end up with wobbly edges. The marker is a small step that saves BIG time on rework. It's not extra work, it's smart work.

Oh, I did the same thing years ago. I kept messing up scrolls because I'd heat the wrong section and the bend would fight me. Drawing a line with soapstone showed me exactly where to focus the flame. It comes right off with a wire brush once you're done, no trouble at all. For twists, I'll sometimes mark the center and the ends to keep everything even. What kind of soapstone are you using, the pencil or the chunk?
