During the last two decades of the 19th century, several companies in England as well as the United States produced a type of glass popular at the time called slag glass or as English referred it, malachite glass. The items were pressed into molds, many of which were very detailed in patterns. Since the colored glass was mixed in various proportions while liquid, the shades and color streaks vary greatly. I have also found over the years that many of the English slag pieces were unmarked as is the case with this example. I have had this particular shape before but in a much smaller size, possibly a ring box or trinket box. It is an extremely rare shape, tough to find in the marketplace today. As mentioned earlier, I could not find a mark on either the base or the lid, seems the piece I had a few years ago had the Sowerby mark of a peacock head. Upon research, I have not found the Sowerby company to have produced this shape. Nonetheless, it is definitely of English origin prior to the turn of the 20th century. The drum pattern biscuit jar stands 6 1/2” to the top of the hat shaped finial on the lid. It measures 5 1/4” across the top and bottom. The bottom and underside of the lid both have been factory ground around the rims, edge at original production. Typically early English slag glass will have various factory flaws such as rough seams, straw and anneal lines, unfilled bubbles, etc. Pictures of the bottom of the biscuit jar shows a couple of burst bubbles as well as some very minor chipping around the rim. Some of this could have been caused during production or possibly from use. None of these detracts from the value or beauty. I also noticed some very minor chipping on the inside rim where the lid sets on the base. In the area of the inside rim of the base, an anneal line in the glass is visible, about 1/2” long-a common occurrence with early slag glass. An absolutely beautiful item, in a rare color and shape ready to put up on your shelf. Please enjoy the numerous pictures accompanying this listing.
