Blast Furnace, (slight) remake of Iron armor & forge

If these things are already implemented in, I'm sorry.

Blast Furnace!
It smelts items at a slower rate but doubles the output of Iron or Gold, also can properly smelt (not damage items...) armor or tools (diamonds can not be smelted down).
Steel! However can be obtained from the Blast Furnace by putting in Iron Ore, the output would be 274 (Iron)x2, Iron would be replaced and renamed to Steel, the iron/steel would have a different texture in this sense (whenever the texture pack comes out).
This basically renames "Furnace" with "Blast Furnace" and changing the time/ticks by changing the time required to 800 ticks, which would take half a charcoal/coal. This would be quite long but worth in-order to get Steel.

Steel (armor & tools)!
Remake of Iron armor in a sense, creating the Iron armor will create a different name; Steel <armor piece/tool>. The durability on the Steel is a bit higher, approximately 1.5x higher (Ex. 360 on a chestplate from 240). Again, same texture as the Steel in the texture pack.

Forging! The power of pressing the metals together!
These have crafting tables which allow you to crate tools and such. They are also home to Blast Furnaces.
