The FS will break down to make Small Piece of High Quality Ore (3 of these combine to make Small Bricks) and/or
Small Brick of High Quality Ore (3 of these make Large Bricks)
To break down the FS you put an FS wep and a Water Flask into a Forge and combine (you will get varying quantities of Small Bricks and Small Pieces of HQ ore depending on the FS weapon you put in the forge... hope this helps
EDIT: The Large Brick of High Quality Ore then makes High Quality Rings: File, Water Flask (1), Large Brick of High Quality Ore (1) in a Forge.
