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

about the mixes that make colors and how the mixes are affected by

You haven't even told us what base glass you want to do this with.
Red is the hardest color to make and to make behave when you use
it.
People who succeed may build an entire company or product line around
it -
for example Blenko's cranberry.
If a perfectly good red mix is mishandled, you end up with kind a
muddy
brown called liver.
