A friend of mine collects old fountain pens.
Frequently the barrel and the nib are sealed with shellac.
He needs to soften and remove the shellac to restore the pen.
The barrels may be of wood or plastic, the nib is of metal of course.
Can you recommend a method of removing the shellac without damaging
the plastic?
Thanks
Jerry

It's usual to do this over a spirit lamp. A candle will work too, but
tends to be sootier. It isn't hard, but don't learn it on your oldest
and rarest first! Very little heat is required. Don't use an electric
hot air gun!
You might also like to read the very active
alt.collecting.pens-and-pencils group (I might have the name wrong)
where such things are frequently discussed There's also the late
Frank Dubiel's book on the topic.

Because using heat is quick and localised. There are a lot of things on
a pen (including other shellac-locked attachments) that you don't want
to dismantle at the same time.
Also I doubt if soaking would work in any useful time. We're talking
about a shellaced screw thread here between two thin-walled cylinders.
Heat through the cylinder is a short quick path, alcohol along the
joint is a long and narrow path that would probably take weeks.

Ahhh, I see. Thanks for the explanation -- I really had no idea.

Shellac dissolves in alcohol/ketones, is eaten away by alkali. It also does
melt. Curious - why risk the melt with the other two obvious choices?

Thanks people
This fellow is newsgroup savvy..I'm surprised he doesn't know about
the usenet group on collecting pens
I'll let him know
