Hi Jacqueline, it looks like an Iron Chromate and Iron Oxide blend to me. I've got some samples from way back somewhere in the studio, I'll have a look in the next couple of days.
If you are serious about getting close to the tone and saturation there is a very useful system to use by casting a wedge shaped piece of glass from every sample you make. Firstly, it gives you a calculable colour density at any given thickness. And secondly (and even more usefully) it allows very quick tonal variations to be seen with variable thicknesses of two or more glasses.
Curious to know how much you will need to melt for your project?
