Abstract: A method of making a yellow, transparent tempered glass and the product so made that comprises adding a certain quantity of CeO2 and TiO2 to the glass composition prior to a rapid cooling of the composition. Each additive is in the amount of about 1% to 6% and together they produce a yellow color. Also, at the same time, from 1% to 5% of BaO or PbO is added as an additive for enhancing the transparency and refractive index of the glass. The resulting yellow transparent tempered glass is especially suited for use in a reflecting roadstud and used for separating the traffic lanes on roads.
