Re: Dry marking pens

From:Shirley Powell <powell_sa@Mercer.EDU>

Hi Steve,

I do not know how to get the pens going again, but I can tell you how I keep
them from drying out so quickly.  If they are stored with the tip down the ink
lasts longer.  I fill an 8 oz specimen container about half full of paraffin,
let it start to solidify, then place a  pen with the capped tip down into the
center of the paraffin, making sure it does come too high to cover the cap and
let them completely solidify together.  When labeling the pen can be rested in
the cap to slow the drying down and when not in use push the pen down tightly.
When that pen is used up, just place a new pen in the cap; they usually fit as
well as first one.  They still dry out, but not as quickly.  If this is not
clear, let me know.
