I am going to be making several optics, mirrors and lenses and will need an Optical
Blocking Wax or Pitch.
I went to Universal Photonics, to see what was available...many products.
What would anyone recommend for the type and where does one get small quanities...like
a pound or so...not huge amounts...
Or, can Gulgoz Pitch be used...as I have all the grades of that ...also Casting Waxes...
