A way to create more ores without mining.

Alloys are a material that are a combination of two metals. Some real life examples are Brass, Galinstan, and Silicon Steel.

I think a new block called the welder should be added which is like a furnace, but it takes in two ores and spits out one alloy.

Alloys could be used for many things such as new redstone mechanics, new building blocks, and to update existing crafting recipes (e.g. Powered rails could be made with bronze instead of gold).

Here are some examples of alloys that could be crafted:

Bronze (Copper, Iron)

Steel (Iron, Gold)

Cast Iron(Iron, Coal)
