~~~ explained to me in depth a long time ago about the danger of even a slightly warped of overly-dried clay composition chip cracking or causing an inlay to pop when a page or several pages comes down on a page which might even have pages with unevenness below... or all the pages coming down on the last page when viewing is complete and, the other danger at a show is stacking several albums on a table while the "flipping" is doing on -- especially when slot tokens are adding to the weight of pages. We, the owner of the albums will usually use caution when going through our albums but, there are no guarantees in how someone else is viewing those pages should you turn away to help someone else... I have even seen a stack of at least six albums dropped on to another stack of albums stored on the floor behind a table...
