蜂窩陶瓷焊接塊

I went with the rectangle block since it fits my bench better, and the ceramic barely warms up even during longer soldering sessions. The little honeycomb cells keep tiny jump rings from rolling away, which honestly saves me a lot of crawling around on the floor.

I've been soldering jump rings on this rectangle block for a few weeks and the honeycomb surface holds pins exactly where I stick them, which keeps my pieces from shifting mid-flow. The ceramic barely warms up even after a long session, so it's comfortable to work right on my lap.

The honeycomb holes hold my pieces in place way better than the flat block I used before, and heat doesn't seem to travel through it much. Only thing is the rectangle is a bit heavier than I expected, so it stays put on the bench rather than moving around with me.
