Antique Qajar Bottle With Unique Unknown Glass Flask

I found both of these at a estate sale.I'm real familiar with Persian antiques especially anything made of metal and knew the stoneware bottle was called Qajar and is the real deal based on the color of sand used on the bottom but the glass bottle flask is really unique.It has seams on each side that go up to the top and has a almost inch thick bottom.There's no marking of any kind on the bottle.It does have a ridge on the bottom and the bottom piece of glass is a separate piece that's a 1/4" thick.You can see the seams all around bottom.I thought it was real green glass but when I washed it some of the green started coming off.Ive shown this to several bottle collectors and nobody can figure out what it was used for.I don't think it's a licquer flask as it doesn't hold much liquid and I bought a book on rare medical and poison bottles and it wasn't there either.It measures 5 1/2" tall by 3 3/4" wide.Does anybody have any ideas.
