Thanks to everyone for their sources for finding Mica! It has been
Here is a little more info I received, just in case anyone else
might be interested...
I sent a query to Ashville Mica www.ashevillemica.com this is their
response: Thank you for your inquiry. For your trials, you can work
with mica intended for stove windows. It is split to a thickness of
approximately .003"/.005" and can be carefully cut with scissors or
an exacto knife. Check your wood stove/fireplace supply company or
hardware store for "stove mica".
FYI...I did go to a local woodstove/fireplace shop and was able to
find an ash colored mica 3 x 5" for $4.50. I was told that they
typically do not order clear mica because it is more expensive and
not of interested to their customers.
Another source was American Science & Surplus www.sciplus.com If
you've never been to this site, it's interesting! A very odd
assortment of stuff.
Thanks again for your help!
