Is the core of foam-core acid free? How about the gasses inside the foam? How can I test this? I have a tester for mat board, will it work on foam? I am sure if I were to ask Crescent or Bainbridge they would insisted their products are acid free.
My experience with "foam" products (foam rubber, styrofoam, etc..)is they deteriorate over time.
