Sigils, what to make them out of Options

Hi, me again. I jus need help with one last thing. I got all the tools I need to conjure Ose (he wont be the first, vassago will). Im looking at the metals to make sigils out of for certian demons, and Ose is mercury. Does any1 know where I can get sum mercury, does it even have to be made of mercury?

thanks

There is a way of 'fixing' mercury using an electroplating technique. This will give you an electrically bonded coating of mercury to another metal anode. The 'fixing', unfortunately, is not stable. It will deteriorate. unless stored in a neutral environment. Stick with zinc, silver, tin or....parchment. If using parchment you can always infuse the fibers with a 'mercuric' solution before the drawing of the sigil. This method is effacacious and inexpensive.
Warning - Mercury, though obtainable, is toxic...when heated it will produce toxic fumes, etc. It's considered to be hazardous waste. (I've used it for years...but then I've had lab training...) Don't mess with it, you may be up on handling it but if you've a family...all bets are off.
