AnalytComments: The body of the piece was sawed and examined without disaggregation because of the vitrification. It consists primarily of light gray and black glassy material with small patches of light to medium green glass. Weathering along some edges is pronounced revealing an original quartz rich matrix. Grains are clear to reddish, subangular to subrounded, and range up to ~1.0mm in diameter. There is no evidence for the former presence of organic matter. The bubble on the surface has a broken section revealing weathered material beneath the glass. It is very quartz rich and may be the remnants of lagging, but the evidence is not conclusive. The grains seem to be smaller in general than those in the matrix.

DK 2087/400<br>Body fragment.The piece is vitrified but shows strong surface weathering. The exterior surface is very rough and has mottled colors, but mostly 10YR 6/2, light brownish gray. There is a large rounded vitrified â€œbubbleâ€ or mass on the inside surface, ~1.0 x 1.5cm. The â€œbubbleâ€ is lighter in color, ranging from 10YR 7/4, very pale brown, to 10YR 6/4, light yellowish brown. There is a light greenish white glass on the underside of the bubble where it is separated from the interior surface in a groove ~5.0mm deep, 8.0mm long, and 1.0-2.0mm wide. Remnants of a dark brown glass, 10YR 4/3, line part of the base of the bubble and up onto it at one end. The surface of the bubble is quite frothy in appearance with remnants of small gray, black, and brown glassy bubbles. Temper is quartz sand.
