I don't get it why Spectrum won't listen to the industry they are wanting to serve.
They are relatively recent entrants into the glass blowing scene and one would have thought they would want to carefully canvas expert opinion before they offered their product. To put out two cullets, neither compatible with each other (which they advertise) and neither compatible with the defacto standard of SP87 defies logic.

SP gave their recipe to me on a handout they gave anyone that asked in 1989. At that time I believe the recipe was public knowledge. I gave it to Spectrum in the obviously naive belief it would benefit them to have a yardstick they could measure their product specs against.
