Cast iron teapot shaped lantern, caged glass. Age?

Recent thrift purchase. How old is this? I have not cleaned it, my first thought was that it wasn't all that old (as recent as 1990s?) but had just been outside a long time. Cast iron I think and fairly heavy. Glass reminds me of Mexican caged glass pieces. Would I call this "caged glass"? Looks like it might have been painted or stained black at one time.

The bottom unscrews so you can put a light inside. Has anyone seen similar? Curious about age.

Sorry I have not touched it as far as cleaning and looks like it spent the last decade outside.











Forgot to take a photo of the top, but the lid is removable with 3 screws.

 

"Blown out glass" along with caged is another term I've seen used for years.

 

Thank Laura.

That search term pulled up this one on Ebay:

Vintage Incense Burner - Cast Iron & Hand Blown Glass 6" x 8" Teapot shape



So thinking vintage at best.

 

This one says new, never used, but no original packaging or stickers / labels. Seller is using the term wrought iron, but I think it is cast iron. No good info, but at least you can see there's another one floating around out there.
