<p>[QUOTE=&quot;gregsglass, post: 3184, member: 78&quot;]Hi,</p><p>&nbsp; Easy scienific way to tell if things are marble or alabaster. marble is calcium carbonate. Alabaster is calcium sulfate. make a tiny scratch on the bottom. Using a loupe to see put a drop of white vinegar on the scratch if&nbsp; tiny bubbles or fizz it is marble. No fizz it is alabaster. Besure to rinse off the scratch. Some people use lemon juice but that stains, the same with red vinegar.</p><p>greg[/QUOTE]</p><p><br /></p>
