Yes you one could can on a glasstop stove but its far from ideal as its slow and i find it to be inconsistant in heating and cycles. In other words its not optimum and maybe some glasstops arent suitable across the board but ive dobe it on ours.
The best setup is the Camp Chef gas stoves an All American can er and that Ball Book of Canning and some tongs and an wooden table on the patio. Makes fore a great setup and i love the simplicity of the All American canner.
I agree with what was said about the chunks of meat looking like dogfood and it does. But man does that canned meat tastebgood and its basically a blank slate for quick and easy meals. My dad shot a whitetail this season and i cut off steaks and canned the rest the next day. Canned an entire moose once as well. Its just an great way to preserve food if done and stored properly. This is an outstanding topic but if you want to be into canning you need the Ball book.
