Why is it that all the things i make involving heat are small?
There's the coal forge, that was fairly diminutive, but i digress.
by-tor the snow dog asked me if the coal forge got hot enough to do glasswork. ( https://www.instructables.com/id/EG8B14NNJJEYMW0DC9/#CEXLBVSRGSWEZ7BDCQJ
) Basically, it does, but i wouldn't recommend it, because the hot coals will stick to the glass ans it'd be manky, so i decided to make a clean, hot-burning furnace using what i had lying around.
