Not a lot to work with but vase is 10 1/4" tall with a slightly irregular shaped rim and has good thickness. Clear base has a crudely polished pontil scar and may be applied to body IDK.
Red with dark strands swirling somewhat randomly.
Weekend find that I passed over a couple of times (vase was really dusty and I thought it was plastic). After finally reaching for it and holding vase, I realized it was handmade. After a lot of cleaning, the quality appears pretty good.
Don't think it's Murano, maybe Czech or US?
Any help appreciated!
