<p>[QUOTE=&quot;Bronwen, post: 400465, member: 5833&quot;]Thanks for this.&nbsp; When I was writing my post, started to mention buffered/unbuffered, but did not feel I really understood well enough to be accurate.&nbsp; As someone with a lot of money invested in calcium carbonate (shell cameos), it has been important to me to know how best to prevent Byne&#039;s &#039;disease&#039;.&nbsp; It seems counterintuitive that buffered paper wouldn&#039;t be the better choice, but can see that it might lead to a sort of contagion unless you changed it regularly.</p><p><br /></p><p>Tom, you will become accustomed to our having side conversations on threads that are about some other thing.&nbsp; It is another way we share knowledge.[/QUOTE]</p><p><br /></p>
