I do apologise for dashing off  I don't think I have ever had to do that before.

As I was saying there is not one layer on the outside of a Realgar bottle but two very thin ones. Look very carefully were the red layer has been polished/ ground down to the base and you can see an equally thin bright yellow layer of glass. This I have never noticed before as I hadn't had the benefit of such detailed images to look at.

As to how this was achieved the only way it is possible to get such a thin layer of glass is to roll the molten base coat in yellow glass dust put in the furnace to melt the yellow glass  and do the same with the final coat of red. Then you could blow it into the mould. Any takers for that idea or does any one have a better Idea.  Regards Jason.
