Everybody! Materials Gathering

Hey Guys, wanted to ask all those pros and noobs to post their material settings (like shaders) for all kind of real or fictional materials.

The purpose is, e.g. :if I want to create a human in a chainmail and some armor and leather parts, which materials do i use for the different parts?
Or I want to sketch the garden, what do I use for the plants, the fence, the chairs, etc.
A quick list with settings to start from would be awesome.

So, I hope you feel motivated and post things like best material settings (and maybe procedurtal textures) for e.g.:
-Brass
-Steel
-Rusted Metal
-Copper
-Glass
-Skin
-Scales
-Wood
-Glossy things
-Water
-Textile: Whool, Cotton, etc.
-Plastic

feel free to post everything you have.
