<p>[QUOTE=&quot;red_spork, post: 2803525, member: 74282&quot;]Distilled water can potentially help but is probably unnecessary at this point if you&#039;ll be using the sodium sesquicarbonate methods mentioned above soon. Really you just want to keep it bone dry to stop the stuff from spreading and you want to get a solution in place before you leave for Newfoundland. I recommend getting some sort of dessicants and Amazon usually has a good selection if you can&#039;t find them locally.</p><p><br /></p><p>As far as why the membrane box didn&#039;t work, there was probably some humidity trapped in there and the membrane held it tight to the surface, helping the BD to form instead of protecting the artifact. I would recommend instead storing it in something like an archival paper envelope or even in the open in a small box with plenty of dessicants to keep the humidity down.[/QUOTE]</p><p><br /></p>
