Make material thick around edges I want to make the material in the provided .blend to be like the provided image. .blend https://drive.google.com/open?id=1ZDs_sCikX-TMTRcuNTmoQeKwBAvsabfk
Here is the solution that I came up with:

1: These nodes are a fresnel node with other nodes to disperse it


The second group is a color ramp to blend in the fresnel to the rest of the material
This is a mix shader to add it to the rest of the material
