Sorry for late reply regarding to your below questions.
“We have bought Agr Polariscope from you - is there any standard photographs by which we can visualize Amber as well as Flint glass container annealing? We can check the same by Standard disc because standard disc is only for flint glass”
We don’t have the standard photographs Polariscope, since we use the standard disc as the reference. You can use same standard disc for both colors.
