The cobalt blue is spectacular on this piece! Google the history of glass rolling pins, very interesting.
Cobalt glass—known as "smalt" when ground as a pigment—is
a deep blue coloured glass prepared by including a cobalt compound, typically cobalt oxide or cobalt carbonate, in a glass melt
. Cobalt is a very intense colouring agent and very little is required to show a noticeable amount of colour.
I do not know who made this particular pin, there were several manufacturers in the cobalt and in this size and style. It is not marked that I can see.
