Doll Leaves Mini [45 cm] Discussion part 4

@Rurimas Hard to say what may have caused it.
If the part that got yellowed was more exposed than the rest of the doll (if the doll was lying on it's back, partly covered, or if the rest was blushed or something like that) it's likely it was something in the air that sped up the oxidization. You say it was a wooden cabinet, most woods are acidic, so in an enclosed space over time that could be the cause. In theory, at least.
But who knows?
Without knowing the casting process and equipment, it's impossible to say if the chest part could have been cast under different circumstances than the rest of the doll. It is true that curing conditions can have an effect of how quickly the plastic oxidizes, so can any pigments and other additives. It is possible that the chest part was cast with a slightly different mix for some reason. But since the whole piece is not affected, faulty resin does not sound like likely cause.

In any case, it's likely just surface oxidization and can probably be buffed out with a melamine sponge.

 

Probably it's really something with the chest piece, cause the rest of the doll is totally unaffected! I checked the arms and you can clearly see they're a different hue.
It's not super jarring actually, but if you look close/with the right light it's pretty noticeable.
I'll try to give him a melanine sponge rub and I'll see if it goes away. At least this discovery made me finally decide to sew him some clothes
