This is a Chrysis Egyptian square perfume bottle with ground neck and bead rim. The perfume was sold by Richard Hudnut and he used his personal name as the trademark, which was registered in 1880, and the company was sold in 1916. Mr. Hudnut had transforming the family drugstore into an elegant showroom. This explains why the bottle has a druggist style shape instead of a perfume style shape. I could not fine information on the bottle itself, there is no makers mark on the bottom just a emboss sunburst pattern. The label is the only identification for the bottle. I could not find any information on the label. The bottle has some unique features. There are six flaws in the glass but none of them came to the glass surface. They could have develop in the cooling process. There are many small bubbles in the glass and the glass is on the heavy side, which would suggest the bottle was mouth-blown and not machine-blown. However, the glass thickness is uniform and the surface is smooth, which would suggest it was machine-blown and not mouth-blown. The stopper is missing and unknown what type of stopper was used. The neck is ground or etched on the inside like an apothecary-pharmacy bottle and has a bead rim. Glass blowing machines was invented in 1903. The business was operating from 1880 to 1916. The bottle is in excellent condition and the label has some small flaws around the edge. I would guess it was made from 1880 to 1891. This time frame is based on the fact that country of origin markings was being enforced in 1891 on all import products. This bottle may have been made in France.
