Hi.
Sue, sorry but i think your bear needs its bugs scratching , the pontil mark is left by the punty rod not the blowing iron , punty rods are solid and of course blowing irons are hollow , there are some early continental blown pieces which display a hollow tube like pontil mark and its thought this was for economy and blowing irons were also used as punt rods , but in the vast majority of blown glass the punty rod is the creator of the pontil mark,
cheers ,
Peter.
