Hi Suzy, I’ve got a bunch of information on this subject on my site: https://nancylthamilton.com/techniques/soldering/. My opinion: I like charcoal blocks the best – I use them the most and they are cheap enough to have several. I also, really like having a potter’s decorating wheel as I can spin it while holding the torch stationary and evenly heat a piece. Hope this helps.
Hi Nancy. I was wondering if you could tell me what your favorite surface is to solder on. I’m not sure what kind to buy.
