<p>[QUOTE=&quot;gregsglass, post: 222156, member: 78&quot;]Hi,</p><p>&nbsp; To tell alabaster from marble: turn to the bottom and make a tiny scratch. Drop a drop or two of white vinegar on the scratch. Look at it with a magnifier, if you see fizzing, it is marble, no fizzing it is alabaster. Marble is Calcium Carbonate and alabaster is Calcium Sulfate. Be sure to wipe off the vinegar so it does not stain the piece.</p><p>greg[/QUOTE]</p><p><br /></p>
