Hi Karen,I'm an italian artisan I work and restore Scagliola and at the moment I was spending my free time (I'm on holiday for a short time)in internet looking something about scagliola.
This site is very interesting and I find funny that there are so many people interested to this material.
Probably if my english is enough good I could help you or someone else.My e-mail is info@artelier-roma.com and my web site is www.artelier-roma.com
Buon anno Walter Cipriani
