Glass Color Information
 

Search enough of the web to find glass color that I can make myself
but didn't find anything useful.

What metal / metal oxide do you use for make glass colors like Red,
Blue, Green.

Any help or pointers on the net would be appreciated.

Thanks.

You could look at http://www.glassworksservices.co.uk/ . I couldn't see
the information with a quick look at the web site but they did have a
table of colours / materials / conditions in their 1st February 2005
newletter. I not on the website maybe they would provide it by email.

this site lists a few metal oxides and what color they produce:

The easiest way to get this info is to look at glazes for pottery.
Here is minimal glass information with some links to more info

Adding color chemicals to a basic glass formula can change the COE and
other characteristics, so it is more than just throwing a chemical in.
Further, getting the same color each time, if that is what you want, can be
exciting.

Thanks for you links guys .. but still I need more info.

like for making red, i need copper but some mention selenium ..

even for blue or green - what are the alternatives to cobalt ?

Thank you so much

From the glassworksservices data

Colour Variation Material
Conditions
Red Ruby Se + CdS not in PbO glass
Reduced + on reheating
Au
Copper antique ruby Cu2O
Reduced + on reheating
Red violet MnO2 + Se Oxidised
Wine red Nd2O3 + Se
Not oxidised

Blue Blue CuO & CoO
Blue (viloet tint) CoO
Sky blue CuO
Blue green Fe2O3 + CoO, Cu0 + Cr2O3, FeO

Green I'm not going to type the following 14 combination of
elemental oxides in for varying green colours at the moment
I suggest you contact www.glassworksservcies.co.uk

There are lots and lots of sources of information, which require that you
spend time learning
about the mixes that make colors and how the mixes are affected by the base
glass.
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.

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.
