It's interesting to hear that you mention alluminium printing plates
because I was thinking of using them but maybe they wouldn't be
reflective enough. I am currently using Mylar. I can't complain
about the reflectivity of it but I've only had it a couple of months
and it's already deteriorating. It could be the way I've glued it.
There seems to be a lot of expansion in either the Mylar or the
Corflute sheeting I'm using when it heats. I am using a thin Mylar
film. I might be better with 2 mil or thcker or laminating the film
behind Polycarbinate sheeting or something.

I used the 5 mil silvered both sides stuff from mirrorsheeting.com.
I never glued it to anything, I just laid it in forms for testing. I took
frozen water to steam in 20 minutes with a 20" x 4 foot trough in
30F ambient at Lake Tahoe. That convinced me that it really "cooks" :)
