Hi folks
Can some of you in school (or in practice) just list again the differences between these two materials?
Off the top of my head...
Zyl frames (cellulose acetate right?) typically has the metal wiring in the frame, optyl does not.
Optyl is transulent, zyl can be opaque.
Zyl is cheaper than optyl I think.
I believe you should not use a bead bath to heat/adjust one of these two frames. Which one is it and why not?
Please comment on the above (did I get them right?) and if you can, please list any other differences.
Thanks.
