A neighbor was cleaning out an outbuilding and gave this bowl to me...covered in dirt and mud. It is unbelievably heavy weighing 8.4 lbs! Not clear glass as pics show but kind of a grey/lavender in the sun. It glows purple under blacklight with pale green along the seams and tips. 6 1/2" tall and 12 1/2" wide at top. I believe it may be manganese glass which would make it quite old.
Any idea as to era made and does it have any value. No chips or cracks..a few bubbles.
Thanks in advance,
