I think the colour of this one is something else (probably lots of manganese?), and that pontil looks high quality - this must be a keeper. The process seems to have been around since the 1870s, though this one is almost certainly much later - maybe 1930s - 1940s, and possibly eastern Europe? The handle is a 'bottom up' job. Used to see a lot of this type in the form of vases, waisted shape often, and in uranium too, but currently a dearth of the stuff.
