This is a super crude 8-sided umbrella ink with shear top and loads of marbled crudity in the glass. Just look at the neck, which seems like the glass blower had a bad day, with a bulge of glass. Possibly Stoddard. Nice tubular open pontil with a chunk of glass that can cut you, and a hinge seam across the bottom.
