Dyottville Glass Works flasks

Two flasks purchased by John Lawry at the 2010 South River show. The quart is a GI-37 Washington/Taylor in a light sapphire blue with an open pontil base. This example has a base chip, a large open bubble on the Washington side as seen in the photo and it retains a light content stain. The pint is a GI-38 Washington/Taylor in a very dark violet or amethyst coloration. The coloration in this example is so dense that hardly any light can pass throught it. It retains some high point wear and surface scratches.

Here's a nice grouping of Washington/Taylor flasks in John Lawry's window. Many of them were blown at Dyottville.

Newly Discovered William Rex Soda

Here is a newly discovered open pontil W. M. REX / 211 GREEN ST // c // porter variant. Unearthed in Philadelphia, PA – and brought to light by Matt Waholek the week of February 23rd, 2014. After bringing this soda to the 2014 Baltimore Bottle Show on March 2nd, consensus among collectors - including Tod Von Mechow of, Kevin Kyle and others - this Rex is an 1850's 'one off' - pretty much a fluke. With all other known examples baring the improved pontil or 'iron pontil' - this 'one off' was probably made because on that day it just happened in the glasshouse (probably at a Philadelphia or South Jersey glasshouse).

Philadephia Redware Pie Plates

Pie plates were a common everyday item used in the kitchen for centuries in Europe and in America. Early Pennsylania German potters were influenced by German sgraffito plates. Sgraffito is a technique in which the body of the pot is covered over with the slip of a different color clay. The coating is carved away to exposed the diferent colored body of the pot. Slipware usually occurs as an earthenware body that has been decorated with slip or liquid clay. Slipware was introduced to this country by the Netherlands in the late sixteenth and early seventeenth centuries. Soon after the English Staffordshire tradition was born. Slipware began to be made in Sussex, Kent Somerset and DevonCounties. It is the wares produced in these English counties that influenced the local American potteries that produced earthenware pie plates. I am guessing that local earthenware pie plate production started soon after settlement in Philadelphia. These wares were not difficult to make and were essential to everyday life. Raw materials such as clay and wood for firing were abundant in the area. Whole Colonial examples of slipware or sgraffito pie plates are rare. The earliest examples at the Philadelphia Museum of Art are from about 1792. There is an entire reference book documenting the Museum's collection. Most of the plates seen in this photo album are c. 1840-60. They are all dug from privies in Philadelphia and restored. In about 1860 the popularity of earthenware decorated vessels and plates plummeted. People began to favor the cleaner looking yellow ware pottery made famous by the Bennington, NH potteries.
