Hi, everyone! I got a jar of marbles at the thrift store and was excited to find some glowers, Vitro All-reds, and my first clay marble! I’m still working on identifying all the others, but these three gave me pause. The first two have marks that aren’t damage, but more indicative of being made before the glass cooled. The blue and white one is UV-reactive. The last one almost got tossed in with the clearies, but then I noticed the wisps and what almost looks like a pontil mark. My guess is that these are Yasuda Transitionals or possibly Seike? Any help would be appreciated. The marble world is fascinating but unbelievably complex.
