Using the furnace is such a pain now, the count of hitting the stone that comes out of there isn't stable, some time is 2 sec sometimes is 1 hit, is a surprise every time. so it often wacks the furnace at the same time and losing coal or replacing the furnace in the meantime is a bit annoying.
The solution i propose, the sledgehammer which was for making sand initially out of the furnace, now we have sand in abundance and we don't even need to use the sledgehammer anymore, could this be a good alternative to destroy the furnace instead, or a pickaxe/axe?
