HI ,
I have to agree with both Steven and JP on the Y and T marks being the result of shearing , the gadget merely being the tool to hold the glass by foot after shearing ,whether the use of these died out around 1890 I really have no idea,I can imagine in some places it may well have been used till a later date , just as we see snapped rough pontils on relatively new glasses at times ,indicating that they are hand made but not necessarily old,
Re Bridgitte's glass ,this to me looks crudely made probably for tavern use , the other i think is much better quality,mould blown in the traditional way ,a 1 piece mould with the bowl then being blown larger after coming out of the mould ,as opposed to the multi part moulds that would create a finished item with seams .
cheers ,
Peter,
Back to the packing for tomorrow!!!!
