<p>[QUOTE=&quot;Smojo, post: 2650355, member: 78058&quot;]I know there are some chemists that are collectors here. I was looking at silica today and had never thought about this, I even googled and wiki&#039;d it but didn&#039;t find a real answer. So I need to ask some fellow collectors their thoughts.</p><p>Is Cobolt Chloride a problem being stored with coins?</p><p>I know it&#039;s a plus to be able to just look at a color and know if the beads are still good or need changed. I also know at a point it can cause health issues.</p><p>But is there any other concerns with it? Is it safe locked up with coins?[/QUOTE]</p><p><br /></p>
