John,

    You lucky dog! Take me with you. I won't be any trouble. Maybe you can sneak me on the plane as carry-on luggage. I promise to be quiet. <GRIN>

  Well...
  I know that samples in Museum of the Earth in Warsaw are labeled using acid free paper.

  And the funny thing is, the bunch of Colombian copal that I have show no drying out or crazing at all. None were polished, but many are broken, with "fresh" surfaces.
  I understand from people in business that there are two kinds of copal out of Colombia. One, lighter in color is not usable for heat treatment at all, the other one, darker in color is the one used for substituting Baltic amber.

  On the subject of using man made resins to stabilise and protect pieces of amber. When done properly you will not see any change in your piece at all. It is just a clear, invisible to a naked eye coating.

  Tomorrow night, I am off to attend Amberif. YES!!!

    Chris,

        In your experience, how is this stuff different from the more traditional epoxy resins? Do you still have to pull a vacuum to remove air bubbles and get the resin into all the cracks and crevices? Also, the fact that it's described as biodegradable has me wondering as to how long it will last once used to encapsulate the amber. Sorry for all the questions but the Ward's site doesn't give much info. Thanks.

      Hi Everyone:

      I have experimented with bioplastic resin. It works wonders with very brittle New Jersey ambers. I embed the piece in the resin and then polish one part back to the amber. The hard resin stablizes the amber. Search the term "bioplastic" online and you will find suppliers. It is expensive also. I got mine from Wards.

      This brings me back to a question I asked the list 3 months ago, which noone gave comment to. A lot of time we bag a piece of amber with a paper label. Can paper, which often has an acid content to it, cause amber to change chemically? John, your the chemist... any ideas? I have started to double bag pieces with the label in the second outer bag separate from the amber piece as a precaution. Some pieces of paper in with pieces from the DR and New Jersey chaged color over time from the amber. I did not see this effect with Canadian amber, Burmese or Baltic.

      My two cents...

      Pax, Chris Albrecht
