This is an Antique Austrian Cut Glass Monteith Bowl w/ Sterling Silver Ornate Base. Information on the Silver Hallmarks: It is marked with a 13 in a square cartouche for the silver content of .812 1/2 fineness per 1000. ( American silver is 925 / 1000 for comparison) We inspected the Silver base more closely with a magnifying loop and did not find any other marks on it that we could see with looking it over. It does not mean that other marks are not there or worn so you can not make them out. It does have some little dings on the Silver base as it is hollow and has a heavy paper bottom over the base that it is now not completely covering the whole bottom and looks like it is filled with a thick waxy yellow rosin.( We have added photos of the Silver Hallmark and showing the bottom of the Silver Base ) We would date this piece from the 1850 to the 1860's. Measurements of the Glass Bowl and the Silver Base: It measures 7 7/8" tall at the highest points of Glass Bowl by 7 3/8", 4 1/4" across the silver bottom Square, the silver base is 5" tall, 21 3/4" all around the glass bowl. It has (14) points on the glass bowl. Information and History on Monteith Bowls: Monteith, a bowl used for the cooling of wine glasses. The rim has depressions in it that allow the leg of the wine-glass to be caught by its base, so that the bowl of the wine-glass dips into ice-water, the base staying dry. Wine glasses rest, upended, in a superbly decorated sterling-silver bowl that has been filled with ice. The stems, easily accessible to guests and servers, lie in depressions around the notched rim of the hand-crafted vessel. Once the fragile glasses have been chilled clear through, they will be removed and filled with warming sherry. These bowls were often made out of precious metals, and being novelty pieces their rarity has afforded many of them great value as collectibles. The name of the bowl immortalizes its inventor, 'Monsieur Monteigh'. Additional information about Monteith Bowls: Towards the end of the Stuart period there came into extensive use a bowl made usually in silver, although occasionally in pewter, known as a Monteith Bowl, with a movable rim, in which semicircular pieces were cut out at the top and their edges highly ornamented with scroll work. It is believed that they were originally intended to be a kind of wine cooler, but they very soon became known as Monteith Punch Bowls. Like the cardinal who gave his name to the Bellarmine jugs. New things produce new names, and thus Monteith has by one vessel saved his name from death. (King.) The first time we hear of this particular sort of bowl was when a well known antiquary, Anthony Wood - wrote the following in the year 1683: This year came up a vessel or bason notched at the brims to let drinking glasses hang there by the foot, so that the body or drinking parte might hang in the water to coole them. Such a bason was called a ` Monteigh ' from a fantastical Scot called 'Monsieur Monteigh,' who at that time or a little before, wore the bottome of his cloake or coate so notch. It is in great condition, other than one of the higher points on the cut glass bowl is chipped and the Silver Base has some little dings around it. What a Wonderful Centerpiece Bowl this would make on your sideboard or dining room table for display.
