WARNING: This mod could be used to create a modpack with a mod that customizes recipes, such as Kubejs.

This mod adds a new ore called cinnabar, which can be smelted (in a smoker; sorry, but I have no idea how to fix that issue) to obtain mercury.
This mercury is impure; it can be purified at the crafting table, yielding two items: purified mercury and cinnabar remnants.
These cinnabar remnants can be smelted again to obtain more mercury.
It adds a new useless stone, quartzite (if you use the Create Mod and are editing recipes, you can make grinding quartzite yield cinnabar; this is just an idea).
It adds two more new materials, each more useless than the other:
The leaded ferrosmium ingot, with no recipe created, and its only use is to make a block of this material.

The silver amalgam, with no defined recipe, also adds a block of this material. You can craft a bottle of mercury, which is completely useless.

And finally, the most useful item, the sieve. It doesn't have a crafting recipe, but if you somehow manage to get one, you can place it. On top of it, you can place four different blocks to obtain a different item:
1. If you place dirt, there's a 1/10 chance of it dropping a pile of copper nuggets, which are completely useless.

2. If you place gravel, there's a 1/4 chance of it dropping an iron nugget, which, surprise, surprise, is actually useful (it's the same as the nuggets in Minecraft).

3. If you place red sand, there's an 11/20 chance of it dropping a gold nugget.

4. If you place regular sand, there's a 1/10 chance of it dropping a pile of tin (also useless).
