I created a Universal Circle on black paper-ish, shown in the picture (looks bright cuz of camera flash). (No materials 
) To make a scrying mirror, can I place a simple see-through glass on its front to act like a scrying mirrror?
I’m confused. What are you trying to do?
The Universal Circle is for the evocation of spirits. It’s purpose is to be a circle for the magician to sit within or to act as a triangle of manifestation for the spirit to manifest in. It’s not a scrying mirror.
But for a scrying mirror it has to be dark reflective right? 
(nvm the uc 
A mirror is supposed to be non reflective. You need a dark surface to gaze into with no light to interfere.
I would assume that to scry into the UC, you would centre it behind the glass so that your scrying surface encompasses the inside of the circle.
Alright 
thank you:)
