Featured Small Cased Red Cut-to-White Lidded Jar, Unmarked

This is really sweetly done. It is ~3 3/4" high overall, ~2 1/2" major diameter, ~1 3/8" diameter ground pontil, 1" diameter chamfered throat; it weighs ~8.1 oz, ~230 grams. There's no UV reactance.
Note the staggered facets in the body, creating elongated hexagonal panels on the two lower rows of cuts; they are also concave in their vertical axis.
What little I know about glass leads me to think it has Western European origin. I'll be grateful to hear from y'all about the reality of this delightful bauble, including what it may have been used for. Thanks for lookin'!

 

A lot of these are Czech

 

Yes...but most Czech glass, in my experience, has been well-marked.

 

I’ve had and still own lots of totally unmarked Czech glass. I think this is, too.

 

I think Peking, jmo.

 

That is a lovely thing... I don't know what it was used for, though.

 

Seems many that pop up are described as Pigeon Squared Peking Glass - Chinese

 

It's very pretty. I wouldn't spend too much time figuring out usage - sometimes a jar is just a jar.
