Yes, molten glass making would be awesome. You can use Novum Cooker to make the soda ash, but there is no bot that currently uses the soda ash and bucket of sand on a range.
Additionally, like others have said the bot sometimes gets stuck when opening the bank. If you babysit it you just need to hit pause and play to make it continue. Although I have found that turning on antiban seems to make it run more smoothly.
