Crystall ball, Scrying Options

I have a lab grown quartz orb about 4" in diamiter with perfect clairity. I wish to use this to scry, where is the best place to learn of scrying or some techniques.
I am greatfull for any help.

To start off someone mentioned an orb, heard that a lot of people see orbs these days and wondered what it meant to someone. It's not quite the same as on the TV program charmed where people would orb from one place to another.

I've been wondering for some time now exactly what people see when they do tarot's, crystal balls or other diviniation techniques. Is it a picture infront of your eyes, in the object itself or a thought in the head?

Thanks.
