PSA: My switch to a lighter touch with hot glass tools

I always thought you needed a firm grip on hot glass tools to keep things steady (like when shaping a piece). But last month, I watched a more experienced blower use almost no pressure with her jacks, and it changed everything. Her moves were so smooth, and the glass didn't get those stress marks I often see in my work. I copied her method on a simple cup, and wow, the lines came out way cleaner. It turns out my heavy hands were actually fighting the material instead of guiding it. Now I focus on letting the heat do more of the work, which feels weird but gives better results. That one demo totally flipped how I approach the bench, and I'm still getting used to it.

Wait, you used to use a firm grip on hot jacks? That sounds crazy to me, like trying to muscle the glass into shape. I always figured too much pressure would just make things worse, but hearing someone actually did it makes my hands hurt just thinking about it.

Honestly, the subtle art of burning your fingerprints off. I get it though, it goes against every instinct to really bear down on something that hot. But josepha32 is right, that timid little pressure is a one way ticket to a cracked piece and sore hands for days. You have to be firm and smooth, like you're convincing the glass to move, not fighting it. If you hesitate, that's when things go wrong. The glass will feel your fear.

Yeah the "hands hurt" thing is real. I burned myself bad once trying to be gentle with tweakers. Started wearing thicker gloves and really leaning my weight into it from the shoulders, not the wrists. Sounds wrong but sometimes you gotta commit to the bend. Found it actually cracked less when I stopped being shy about the pressure.
