Show sample as: 72-frame QuickTime VR or 360-frame QuickTime movie loop.    My periodic table poster is now available! Slab. More than a mere square, much thicker than a foil, this is a slab. I acted as a transshipping point for a set of five of these on the way to Max Whitby at The Red Green and Blue company in England, sells a very nice element collection in several versions. (To learn more about the set you can visit my page about element collecting for a general description or the company's website which includes many photographs and pricing details.) I chose this sample to represent its element in my Photographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.
