Metals+

It would be cool if there would be brand new metals like:

-Lead (you could make pipes out of it for easier transportation of liquids with pumps, valves and tanks, it will be found mostly in the deepslate layer)  Color: Dark Gray 

-Tungsten (could be used to make weights out of to make pulley system elevators with, it will be found in the higher parts of the Nether) Color: Dark Olive Green 

-Titanium (will be used to make special anvils, will also mostly be found in the deepest parts of the overworld) Color: Marine Blue

-Tin (A metal used to make Bronze, will have a similar rarity iron) Color: Mustard Yellow

-Zinc (A metal used to make Brass, will have a similar rarity as iron) Color: Rose Pink 

-Bronze (Will be used to make mob statues, will be crafted with Copper and Tin in the new Crucible block) Color: Dark Reddish Brown

-Brass (Will be used to create special shields, will be crafted with Copper and Zinc in the new Crucible block) Color: Light Yellow

The Crucible

-The Crucible would be used to make alloys with metals such as Bronze and Brass, it would be crafted with obsidian in the shape of an minecart and 2 iron ingots as the legs of the Crucible in the Crafting Table.

-To set up an Crucible you would need the Crucible item in your inventory and place it on a Campfire and you are basically done!

-To create alloys you would need to put 1 ingot of one metal and another 1 of a different metal and place them in a crucible , simple.
