Hello, I am new here. I hope this post is OK to share with you. I'm sorry if it's not. I found this beautiful huge blown glass vase. It was buried in my backyard for at least 20 years! I've literally been online for a few years now every day looking for something that helps me understand why it was buried and what its history might reveal. I'd greatly appreciate any info you could offer. Thank you so much in advance. It's 24" high and weighs about 13 Ibs. it's cased in super heavy thick glass or crystal. It looks black, blue and white but it turns a reddish purple in the light. It does have several markings. I'm legally blind so it's hard to see them. Thank you in advance if you’re able to help! I love it!
