The above reasoning seemed to link the saggers with brown salt-glazed stonewares rather than with products in the Rhenish tradition, which would have been the other obvious possibility.[249] Wasters were thinly represented among the sherds from Yorktown, although many underfired or overburned pieces were initially claimed as such. A more mature study of the Yorktown potter's products has shown that these variations would not have been considered unsalable, nor, in all probability, would they have been marked down as "seconds." Examples exhibiting both extremes of temperature have been found in domestic rubbish pits at Williamsburg, clearly showing that such pieces did find a ready sale. Figure 4 illustrates a mug fragment from Williamsburg with a large, heavily salted roof-dripping lodged above the handle and overflowing the rim, a blemish the presence of which is hard to explain if the mug was fired in a sagger. Such a piece found in the vicinity of a kiln reasonably could be considered a waster. It must be deduced, therefore, that, providing the Yorktown potter's vessels would hold water and stand more or less vertically on a table, they would find a market.
The site of Rogers' kilns in or near Yorktown has not been found, nor have his waster tips and pits been located. In the absence of such concrete evidence, a study of his wares may be thought premature. But, while numerous questions obviously remain to be answered, sufficient data have now been gathered to identify a considerable range of brown stoneware as being of Tidewater Virginia manufacture. There is, of course, good reason to suppose that much, if not all, of it is a product of the Rogers factory, although until that site is dug one cannot be certain. It can be argued, perhaps, that if there was one more or less clandestine stoneware potter at work in the area, there might well be others. It could also be added that two earthenware-pottery-making sites have been discovered in the Jamestown-Williamsburg area for which no documentary evidence has been found. The very fact that such enterprise was officially discouraged reduces the value of the negative evidence to be derived from the absence of documentation.
