I got some silver nitrate on my pencil the other day. Should I wash it or is it fine to use it?

Here is what I found on the internet. I hope I'm not wrong, you might want to check other MSDS just to be sure

Silver nitrate is toxic and corrosive. Little exposure to the chemical will not produce
immediate or even any side effects other than the purple skin stains, but with more
exposure, side effects will become more noticeable. It is very poisonous and can
cause burns. Long-term exposure can cause permanent blue-grey staining of eyes,
mouth, throat and skin, (argyria) and may cause eye damage. Short contact can lead
to deposition of black silver stains on the skin. Besides being very destructive of
mucous membranes, it is a skin and eye irritant.
Silver compounds, such as silver acetate, silver nitrate, silver arsphenamine, can be extremely toxic in the
human body due to the extremely high concentration of silver. All silver compounds used, for a variety of
reasons, place a user at risk for argyria.
The risks associated with use of high PPM silver compounds have been very well documented. Most
compounds available today contain an extraordinary amount of actual silver content (as measured in grams or
micrograms).
So all in all it seems a bad idea to have it on your pencil.

I'd better do something about it. Thanks for the information.

The amount of Ag on your pencil would be in the milligrams amount, nowhere enough for 'long term exposure'. Read any MSDS and they will all spell a slow, horrible and painful death for any chemicals under the sun.
Just don't chew on the pencil, you'll be fine. If you do end up coming into contact with it, I'm sure the chemicals they used to treat the wood and graphite will kill you first anyways. :P

Get a pacer :)

how do you know xD.
Maybe they did an experiment in which they saturated the pencil with silver nitrate. It's better safe than sorry lol.

Seriously guys, how is this a debate. A HB pencil costs 60c, hardly debate worthy :P

I've had some pretty severe stains on my clothes and skin from a AgNO3 incident (and accidentally ingesting some residues when I thought chips after lab is a good idea) :P
I have not yet died from any of the horrible diseases as far as I know. :)

Haha it was a pacer.
