Magnifying Glass (GregTech 6)

The magnifying glass is a tool that can be made using any lens. When placed on a crafting grid with a book and quill and four identical samples of a material (piles of dust, ingots, ore blocks, etc), the magnifying glass loses a bit of durability and creates a book of properties for that material. These books include helpful hints for important materials (magnetite, wrought iron, etc.).
