Not intentional.
The larger the marble more likely the orange peel in my experience--even with Vacor.
Pelt had orange peel on a few black based marbles, as did a few others. some companies just have or had higher standards.
I have yet to see an Akro with orange peel but I am sure that there are some out there.
Masters have not appeared in my home with orange peel and I cannot recall any Vitro either.
In my judgement--it was due to the temp of the glass vs the temp of the rollers.
David McCullough would be the one to give you the best answer.
Give him a try--what the heck?
Marble--On!!
