i would be using Borosilicate Glass.


What terms do I use to search for glass color making techniques on
google.


I always end up on commercial sites which sell colors but very few
sites that actually say what proportion of oxides/metals to use for
different colors.


thank you so much

This is the information that companies are based on, no formula, no company.
you will be hard pressed for anyone to give you the precise information that
you want.

You MUST read, study and experiment and put in the sweat equity to create
that which you seek.
There is no answer to your question.
