Hello girls :-) 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? 1.) On the lower leg, quite in the middle 20151006_203637 by Diana Hinkelmann, auf Flickr 2.) On both lower legs, right in the middle 20151006_203908 by Diana Hinkelmann, auf Flickr 3.) On the hip-joint and upper leg 20151006_203839 by Diana Hinkelmann, auf Flickr 4.) On the arm quite near the hand-joint and on the hip-joint lower then middle. 20151006_203803 by Diana Hinkelmann, auf Flickr 5.) On the kneejoint (lower then middle) and lower leg (middle) 20151006_203646 by Diana Hinkelmann, auf Flickr

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 Your doll has very nice joints by the way

Hi Allurose :-)
thank you for that fast feedback/answer! Yes, her joints are really beautiful and her posing is simply perfect ;-)

I have heard that about the lutsenko dolls. I hope I can handle one myself someday!

Even Enchanted dolls have somewhat visible seams sometimes, it's handmade porcelain and as long as it's not too obvious it does not detract from the doll's beauty (in my opinion).

I've read somewhere that porcelain has some kind of memory of its own and however hard you sand those seams there's always a trace after it's cured. Have you heard of that phenomenon?

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
