This is a gorgeous antique cut glass Bowl. Measures: 12" wide by 4-1/2" tall. It is from the Late American brilliant era entering the Elegant era. Which is over 100 years old now.
It comes from one of the companies that made fine engraved patterns. It does blacklight green with Manganese best seen from the thicker base. The blank itself is high quality and heavy.I have always felt H. Sinclaire co as the best possibility but never figured out who made this beauty.
The floral pattern is well detailed, using many flowers. The deep channel border style is seen in other Sinclaire patterns.
I also think the blank shape is one from c. 1927 in the Sinclaire book vol.
Other experts have looked at it, and cannot identify it as well but agree it could be Sinclaire. Condition: This is 100 years old- but no chips or cracks. There are Minor scratches on inside and outside, and scuffs are usually expected from age.This is for 2 reasons- We sell antiques / vintage goods, therefore they are used, I provide photos of the exact items and not stock pictures so you can always see the exact item you will get.
