Glass plate recommendations

[holocoder]

I am looking to start using HX200 photopolymer and I see that it needs to be laminated onto a glass plate. What is a good source for glass plates? I would like to start with the 10x10cm film, and then eventually try out the larger 30x40cm sizes.

This looks like a reasonable place to start but depends what kind of holograms you’d like to make and your skill level already. Good luck! Link is to 4”x4” on Amazon.
