Can you be a little more in depth?
"A physical scrying mirror works similarly but your getting the added benefit of using the energy of the physical elements that make up the mirror and that you add to it, it adds oomph to the process and also allows you to work with the the energy of those elements if you choose to."
What exactly do you mean? I have never really got the dark mirror to work. I've read look at it with a low light and with candles. And various other things. I just don't know what to try first. I will say for that online mirror, that when I want to see what something looks like I get consistant images. If you would call it an "image". I guess these things are real in their reality anyway.
