Kralik Blue Glatt Silberiris Vase

Found another Kralik Glass Vase on my thrifting trip , again at a donation store ;lucky me but why when so pretty & undamaged . Sometimes I am amazed at the items I find in Goodwill , Salvation Army and Savers ; because of the store acquiring them through drop off donations . This vase on the shelf being one of those items . I buy what I like and this vase was glowing from the shelf , blue ground with a beautiful golden aurene , ground & polished lip; standing at just over 6" tall and a 2" round base .
