32
Q

What is the bloomery

A

Low shaft furnace, about the size of a dustbin with the furnace below ground the slag would be tapped into here. Air was blown into a hole

33
Q

Problems with the bloomery

A

Limited production in one off proces.

Iron bloom contains slag and has to be hammered

34
Q

Solution to the bloomery problems

A

raise furnace temp
Make larger stone furances
Locate near rivers to use water wheel furances

35
Q

Why is charcole important

A

Charcoal is needed to heat the iron

36
Q

Problems with charcoal blast furnace?

A

Needs water to turn water wheels

Deforestation

37
Q

Soultuon

A

Use coal as the energy source

Use seam engines
