Blender 2.93- Glass BSDF node - Basics
(First on Closed Caption)

The Glass BSDF is used to add a Glass-like shader mixing refraction and reflection at grazing angles. Like the transparent shader, only pure white will make it transparent. The glass shader tends to cause noise due to caustics. Since the Cycles path tracing integrator is not very good at rendering caustics, it helps to combine this with a transparent shader for shadows


Roughness: 0.0 gives standard Lambertian reflection, higher values activate the Oren-Nayar
Value 1 = White Color
Value 0 = Black Color

IOR Maps also works on White and black color

Normal Map Works on XYZ Coordinate (No Need to make a high poly mesh)
If you want to add some bumps on object, then choose normal map




Inputs:
Color
Roughness
IOR (For refraction)
Normal

Outputs: Standard shader output.
