Thank you everyone for your responses!! For some reason it didn't email to alert me even though I thought I had it set to.
ESC - I will test for mercury tomorrow, we have the materials in our lab
SGA - I am at the Fashion Institute of Technology, but still a 5 hour drive from the Corning Glass Museum. I did, however, email them and the one in Jablonec yesterday. Still waiting on responses... I will send an email to Ms. Kaspar's right now!
Thank you all again!
