Check out your art departments for a pigment called Vermilion. While most U.S. art paint manufacturers don't use it, the kids and teachers know they can be purchased on the Internet. And a company called "Natural Pigments" will sell you mercuric sulfide vermilion in a powdered form if you want it.

Hi
Brandon:
Is it possible to replace the mercury with other safe alternatives, such as oil?
Thank you.

DCHASers,
We have a building wide lab renovation project starting up that involves ventilation upgrades and installation of sprinkler systems. A number of these labs have
glass vacuum line systems that are 6-12ft long, some containing various mercury containing components. Due to the size and intricacy of the systems, there is a significant hazard involved with dismantling them and the labs would like to leave them in place
and have them protected in some fashion.
Does anyone have any recommendations to have them crated in place or whom would be the best type of company to reach out to? I wouldn't trust a standard crating
company with this project and we are currently reaching out to the local scientific gas blower that made the systems for his suggestions.
Thoughts would be appreciated.
Regards,
