Platinum

Shiny metal (Platinum) is found either in dungeon chests or by pulverizing ferrous ore. Each Ferrous ore has a 10% chance of producing shiny dust when pulverized. With GregTech installed shiny metal and platinum are interchangeable. Shiny Ingots are used in some of the highest tier Thermal Expansion machines. Shiny Dust can be used to save Tesseract settings by right clicking a tesseract with shiny dust. Once this is done you can move the tesseract and it will remember its settings when you place it back down.
