Dear All,
In lead-based glass systems, there naturally occurs a brownish color in the glass body. Similar to the decolorization of iron oxide in the soda-lime-silicate glass system (use of cobalt oxide and zinc selenide), what possible agents can be preferred for obtaining neutral color as possible as it can in lead-based glass systems?
Thanks in advance.
Dear Recep Kurtulus thank you for asking this very interesting technical question. Unfortunately I did not find a suitable original research article which might give you a good answer. I found one hint in the Wikipedia entry cited below, but unfortunately without any reference to a published paper. It is stated there that "nickel together with a small amount of cobalt has been used for decolorizing of lead glass."

There is also a rather old article in which the possible use of rare-earth metal oxides for this purpose is mentioned:

(see attached pdf file)
Good luck with your work! 👍
Dear Frank T. Edelmann
I appreciate your kind interest. Also, I thank you very much for your shared file. I will check it and will try to realize. If I cannot still find out any result, then I am planning to initiate an experimental study.
With warm regards.
Dear Recep Kurtulus
Do you find a best decolorizing agent?
We used the mixture of Sodium Selenide and Sodium Nitrate, and Cobalt Oxide But the produced glasses had the light green color.
We now use a mixture of sodium selenide, cobalt oxide and potassium nitrate. The color of the bottle glass is smoky.
