Dried Kelp Block

"I built myself a house out of kelp blocks! Some people warned me a house built entirely out of underwater plantlife might have a nasty aroma. But as a man who reeks of rotten fish anyway, I didn't mind in the slightest!"

- Tom Stone

Dried kelp blocks are blocks that are primarily used as a fuel in furnaces.

Obtaining
A dried kelp block will be broken at the same speed using any tool or the player's fist.

Fuel
Dried kelp can be used as fuel in a furnace. It lasts 200 seconds, meaning that it is able to smelt 20 items. This is 2.5 times as long as coal and charcoal.
