Ahkeraliisa Riihimaki - Glass thickness question..?

Hi All,

Wonder if anyone can advise, do Riihimaki Ahkeraliisa come with different glass thicknesses..?

I have attached a photo of one I have recently purchased, there is also a photo of a large Ahkeraliisa on this site with a thick rim and neck. The thicknesses of the glass is at least twice or three times as thick as in the regular Ahkeraliisa vases.

Can anyone advise if they are familiar with these or if they have seen anything similar?

On a separate note, has anyone seen any kind of production imperfections or trials of glass under these rims before? - Don't seem as cleanly finished as some of the thinner versions.

All thoughts appreciated.

Best Regards,
Greg
