Thanks again for your input Peter. To answer your question...no. The vase does not look like the white you are referring to(matt cream)has not been added later & refired.
I have added more images, I hope, that show the paler glaze is actually overrun in some areas by the other coloured glazes, however I feel that the creamier prominent looking glaze, is the end result of the finished transmuted colour that was created as the vase cooled to its finished state...only my interpretation.
I checked the adhering bumps & upon closer inspection of all, I found more which actually look like bits of brick or sandy grit...have added images of these....since they seem to be embedded in the surrounding glaze & some partially covered by glaze flow in the kiln? then maybe this contamination happened whilst the vase was in the kiln & had foreign particles dropped on it from some other piece or surface in the kiln? Let me know if my conclusions are valid or not? It's all a great learning process for me & thanks again for helping me to understand more about these fascinating objects. yours humbly, Andrew

flambe vase by: peter
Hi Andrew, The overall appearance of the vase is that it is modern, but I can see why you think it could be not. The bottom looks old.
I have seen a genuine old bowl recently, that also had a white glaze which was in an even stranger state. Does the actual item look as if the white was added to an already finished vase and refired?
Basically, this looks like a firing accident to me. I would like to draw your attention to the fact that if the bubbles do not contain sand or something similar, than the overall thing is strange. If it were fired at a normal temperature, over 1100 degrees, then any bubbles would probably disappear as the molten glaze would become even at the high temperature. So, whatever the cause is, the last firing must have been at a lower temperature, in my view.
This vase doesn't look as if it was intentionally made that way. You should be aware that with wood fired kilns it is difficult to keep the temperature the same in all the kiln, and it may never drop over the days of firing. Accidents do happen...
