VirtualBox does not change the CPU architecture of the host machine, and as OS4 needs PowerPC to run on, this unfortunately can't work. You need full emulation which is always much slower.

Workbench 1.3 is limited in that files without icons can't be manipulated via the GUI. Later versions have the option to show all files (and list them by name instead of icons, among other things).

Is it this stuff (https://www.elcoteam.com/media/productfile/7_149.pdf)? Looks like zinc chloride based flux, for somewhat more crude applications. I'd say don't use it for electronics work.
