Dear All: I used the Pigma Microns consistently throughout college (16 years ago).=C2= =A0 I recently discovered that the black "pigment" Micron writing in my pers= onal journals from that time period=C2=A0is fading and bleeding.=C2=A0 As an= amateur papermaker and bookbinder, I can reasonably argue it is possible th= at the paper is so poorly made that it is the chemicals in the paper that ar= e causing the fading, not the Micron pigment itself that is fading.=C2=A0 Re= gardless, after 16 years in a book on a shelf, these Micron writings are fad= ing, but still legible.
For field work these days, I use ballpoint pen on paper, and Sharpies on pla= stic or wood.=C2=A0 However, Sharpie markings, if in the sun even for a coup= le of hours a day, fade after a year or less.=C2=A0=C2=A0If the Sharpie mark= ings are in the shade, they can last about 3 years.=C2=A0=20 -Melissa McCanna Arlington, VA -----Original Message----- ---------------------------------------------------------------------- Date:=C2=A0=C2=A0=C2=A0 Wed, 6 Jun 2007 06:52:06 -0400 From:=C2=A0=C2=A0=C2=A0 "Quinn, Michael J Dr USACHPPM" <[EMAIL PROTECTED] US.ARMY.MIL> Subject: Re: Pens or pencils for field notes (UNCLASSIFIED) Classification:=C2=A0 UNCLASSIFIED=20 Caveats: NONE When working as an assistant curator for a museum, the Pigma Micron pens from Sakura Color Products Corp, Japan were prized for their permanence.
