Also the new chalk that makes dust that is safer to breathe doesn't write as well as the older kind that is bad for your lungs. Very similar to leaded/unleaded

Very similar to leaded/unleaded solder.
- jacobolus 9y agoLeaded solder is actually generally better for your health (just don’t eat it). The unleaded stuff has really nasty flux, and requires much higher temperatures, meaning the fumes are quite a bit worse. Make sure you have very good ventilation when working with unleaded solder.
- analog31 9y agoCompletely as an aside to the thread, if you're doing this a lot, try Kester K100 alloy, which is much lower melting than the first generation Pb-free, and behaves a lot more nicely. Not like genuine PbSn, but closer. Techni-Tool has spools of it in different diameters.
