Why Do My Objects Render Without Materials? [Ceramic] So, I'm trying to make some ceramic (copied some nodes from online) objects for a practice project, but I can't get it to show up when Rendering. I tried to simplify, just apply it to a sphere, but I still can't get it to work. 
I'm still pretty new so any help would be appreciated.
As Ashutosh said, you need to put some light sources in your scene so that you can see the glossiness of your object. If I create a floor and put two planes with an Emission shader material, it seems like your nodes organization works.
