I've gone with fire-scrying for quite some time now; the flames and coals of a camp-fire are just so much more animated than a mere bit of glass. But to answer the query as to making a scrying mirror, it's been answered---simply buy yourself a glassed picture-frame, pull the cardboard backing, paint the back-side of the glass with black paint, and re-set the cradboard backing once the paint is dry. One note, though; a high-gloss paint will reflect any background light sources right back at you, even more so than the glass itself will...so a flat-finish paint will work better.

 

You can make a scrying mirror the same size as a regular photo-portrait frame; a 5"-by-7" will work nicely; an 8"-by-10" is even better. One word of caution, though: Picture-frame glass is "S" grade (glazier-speak for "single thickness"), and is easily broken into jagged shards. Do not hide something like this where you'll be exposed to very bad cuts---like between mattress-and-spring, or in the middle of a drawer full of clothing. I've seen some that are made using plexiglass (sheet plastic that looks like glass). After a while, they get scuffed and scratched, and then you have to get a new piece to make another "mirror"---but at least you're protected from getting a hand sliced to ribbons, when you reach into the mirror's hiding-spot, and find yourself holding several jagged pieces of glass....

 

If you're making a black mirror, the easiest paint to use is a flat-finish Latex. One good coat will dry completely in an hour or two. Alkyd Enamel, on the other hand, is the stuff commonly referred to as "oil-base" paint. It takes much longer to dry, requires a solvent for clean-up (as compared to soap-and-water for Latex), and you really don't want to paint with AE indoors if it's too cold to leave the windows open, as the fumes are highly noxious, moderately toxic, and very flammable....

Theres a rather large list of scrying, Fire scrying, Mirror scrying, Water scrying, Smoke scrying, Hemite Scrying.

Hi Sapphire,

 It all depends on what you want to use the mirror for. Black mirrors are good for many things. For seeing into the Astral world, divining the future, seeing the past etc.I have found another use for a glossy black mirror that has been blessed with a magnetic strip placed on the back (I also place some sacred symbols on the back in appropriate colors to the symbols), I can use this mirror to inhance a spell I am casting by reflecting the candles and the other items I am using to send the spell into the ethers. It appears to magnify the spell by at "Least" three times over what I have put into it. I'm really being conservative here. Silver mirrors are used also to inhance a spell I may be casting. Lets face it, Mirrors are invaluable when it comes to spell casting. At least in my book.
