Question about Smithing a Silvered weapon

[Stealtheye]

Hi everyone,

So as the title says, I'd like to craft myself a Silvered weapon. A Silvered Warhammer for example.

It's the Enchanted Sheet Metal that's throwing me.
Do I require Large Brick of High Quality Ore
OR
Large Brick of Ore

The spell Enchant Steel says that it requires a Large Brick of Ore to create the Enchanted Ore, BUT the Large Brick of Enchanted Ore page says I need Large Brick of High Quality Ore?

If anyone knows one way or the other, I would be very grateful for the clarification.
