a short time ago I bought a doll from Lutsenko-Dolls. Some may remember my Lilliana ;-)
I have examined her very closely and I saw that she has some strange "seams" on the outside of her legs and arms. They are difficult to photograph but I tried nevertheless. Do you have these on your dolls also? If an artist is reading this: Could you explain how they developed through the process?
This is a natural product of the porcelain pouring process. The pieces are poured in two part molds, with this seam forming where the two halves meet. Some artists are more fussy than others about smoothing the lines so you can't feel them. Even if they are smoothed flat to the rest of the surface some visible line may remain because of the way the porcelain hardened. I have been able to see the lines in at least a few places on all the porcelains I have handled
The seams are normal, but for the sake of aesthetics, they should be polished away as best the artist can. On my Anna K. dolls, I cannot see any seams. On my other dolls, there are only very slight hints of any seam. Obvious seams don't take away from a doll's function or posing, but our eye tends to not like them.
I think it's because when poured into the molds, at the point of the seams there is always more air and the porcelain dries faster, thus becomming a bit more dense then the rest of the porcelain. I've sanded my raw porcelain pieces totally smooth before firing and after firing the seams are raised again. I geuss it's becaus of a different dense-ness it schrinks slightly different then the rest? This is all speculation though ^^ I'm not a professional on porcelain. I also think that if you also sand the greenware again the seams might be reduced to a minimum.
I personally only fire once and see the seams as a sign of being hand made and of the process, my Vividdolls also has them and I adore it

The degree of visibility of seams depends on the kind of porcelain. And on the quality of the plaster molds. Some porcelain slips give hardly visible seams, even with bad molds. But others - a very visible seams, even if the molds were made perfectly.
And yet, as far as I know, the slip flowing between the halves of the plaster mold has a more dense consistency. So after the firing the seams appear
