Thank you for kind words, all!
No, I don't think there's any special significance, except the blue paint was quite expensive in the 18thC, so probably just a status symbol in its day.
Yes, I'll seal it, but just using the turps/linseed oil mix. Anything more would seal the surface completely, and take patina away from it.
Oh, but it is! (Native, that is.) These "tea tables" are quite typically Scandinavian. Here's a last pic, with the lower glass painted a navy on the underside. I had a sample of my sofa's upholstery scanned at the paint shop, the paint turned out quite a bit darker than the sofa, but complements the table well, I think. Anyway, the table will be in another room.
