  Artifacts, Archaeology of Castle Rock Pueblo   (Site not responding. Last check: 2007-10-23)
That sherds identified as Mesa Verde Black-on-white tend to be larger than average is expected, since the classification of local white ware sherds to traditional types relies heavily on the identification of specific painted designs, which are often difficult to identify on small sherds.
If sherd size is primarily responsible for the variation in large size mode development in Figure 4, then one would expect Castle Rock Pueblo sherds to be significantly larger on average than sherds from hamlets for the 14-cm radius class, the class at which the large size mode occurs in Figure 4.
All sherds, both local and nonlocal, from each study unit are included in the column headed "Total Sherds." All but two of the 32 nonlocal sherds (those in PDs 739 and 978 in Table 22, which are from Arbitrary Unit 300 and Structure 402, respectively) were found in excavation units south of the central butte.

 Profile and Axis Estimation
The degree of the algebraic surface used for a particular sherd is the degree that is appropriate to the complexity of the shape.
Accurate estimates of the axis and the profile curve because in the horizontal plane of the pot, i.e., the plane perpendicular to the axis, the extent of the sherd is large enough to measure the curvature, equivalently, the pot radius, and the profile curve is distinctive.
If a sherd is small, it is often the case that it looks like a patch of a sphere, and it may then be possible to estimate principal curvatures but not the axis for the sherd.

 Sherd - Wikipedia, the free encyclopedia
In archaeology, a sherd is a fragment of pottery or other ceramic.
A sherd may be either historic or prehistoric in nature.
Occasionally, the same item may be referred to as a potsherd or shard, although the latter term is generally reserved for glass.

 Ross Island Pots
Macroscopically the sherd has a 2mm wide dusky-red core (10R 2/2 on the GSA rock-color chart) within a moderate reddish-brown, inner and outer margin (10R 4/6) The sherd shows many tabular to angular voids (a "corky texture") which are up to 2mm in length.
The sherd has a uniform, light brown body colour (5YR 5/6) and is lightly gritted with mudstone, banded calcite and quartz clasts up to 3mm in diameter.
The sherd has an even pale reddish-brown, body colour (10R 5/4) and is lightly gritted with rounded to subangular heterolithic clasts including white limestone/chert, rounded sandstone and red mudstone up to 3mm in size.

 6.2.8 Historic Ceramic Analysis
One of these sherds mends with one of the rim sherds; further similarities in paste and glaze strongly suggest that all five sherds derive from the same plate.
Sherd 97-470 (included in the catalogue along with the brown stamped and banded sherd, discussed below) is a blue transfer-printed pearlware base sherd, most likely from a plate.
The latter sherd, if it should prove to be better described as ironstone, might have belonged to the same set as the saucer found in 1997; the same could be true if 97-517 is in fact refined white earthenware.

White ware and red ware sherds are assigned to the jar category on the basis of curvature and the presence of paint, polish, and/or slip on the exterior surface, and the absence of these surface treatments on the intact interior surface.
White ware and red ware sherds are recorded as bowls on the basis of rim form, sherd curvature, and the presence of paint, polish, and/or slip on at least their interior surfaces.
Sherds classified as having carbon paint include those with paint that is believed to be exclusively carbon paint, as well as sherds with paint that is believed to be a mixture of carbon and mineral paint.

 World's Oldest Wine Jar @ University of Pennsylvania Museum of Archaeology and Anthropology   (Site not responding. Last check: 2007-10-23)
Both the jar and the sherd were made famous by widespread international media attention following a June Nature magazine article about the discovery of wine residue on the sherd.
Both the pottery jar and the sherd were recovered in 1968 from the "kitchen" of a mud- brick Neolithic building at Hajji Firuz Tepe, Iran - a site excavated by a University of Pennsylvania Museum expedition under the direction of Dr. Mary M. Voigt (as part of the Museum's Hasanlu Project, 1956-1977).
When a yellowish residue was noted on the sherd, which had come from the bottom third of a jar, Dr.

 Fort Bragg (NC) Ceramic Petrology Photomicrographs - Pottery thin sections
These sherds display oxidation features (commonly a red to red-orange colour) on one or both of the inner and outer sherd surfaces, extending into the sherd for several millimeters.
This sherd shows the blocky to subangular shape of the feldspar and the subrounded to subangular shapes of the quartz mineral and rock fragments.
Colour of these sherds is generally red-brown (brick) and sometimes a thin oxidation zone at the sherd edge is observed.

 Curve Matching(5 points and normal constraint
Hence, one sherd in a pair is held fixed and a best Euclidean transformation is estimated for the other (3 translation parameters, 3 rotation parameters).
With each there are three views of the assembled sherds in order that one be able to see how good the assembly is. In these cases one sherd is held fixed and each of the other two is transformed, which means that two transformations must be estimated -- 12 paramters.
The matching can be improved by using data at the other vertices as well, by automatically adjusting the locations of the first points at the vertices better, and, more generally, by using points along the entire common portions of the break-curves and using denser sets of points and dynamic local curve-scaling during the point matching.

 South Park Archaeology Project
If a sherd contains large inclusions of quartz it was most likely not used for cooking, because quartz “expands much more quickly than clay and can lead to crack initiation.” (Chilton 1999:104) It is important to note that a pot with small quartz particles can still be used for cooking.
As Chilton notes, “a densely tempered ceramic is stronger than one with lower density”, therefore it is likely that densely tempered pots were exploited for their strength and utilized for transporting materials.(1999:104) Also, densely tempered pots are more likely to crack during the firing process due to shock from thermal expansion.
To determine the function of the pot we analyzed the ceramic sherds along the aforementioned attributes: temper type, temper density, and sherd thickness.

In the margin of the fabric of the sherd beneath the exterior of the vessel the fabric is a light, almost salmon pink colour.
The core of the sherd is dark grey and the interior surface is buff.
The sherds fabric and appearance is not incompatible with them being Bronze Age and as is detailed in the flora report below, the assemblage of grains etc from context (139) the lower fill of pit (110) is suggestive of a Bronze Age date for this feature.

 Structural Segmentation of Sherd Surfaces
Generally, the break surface of a sherd is a long and narrow strip as compared to the overall sherd surface.
The inner and outer surfaces of a sherd refer to the smooth regions of the sherd's surface, which are named to correspond with the inside/outside relationship of the vessel as a whole.
To segment a sherd surface into structurally meaningful components (break surfaces vs. smooth regions), we have adapted a method for 2D image segmentation and applied it to the triangle meshes surface representation of the sherds.

If the broken edges of a sherd are obscured by dirt, you should carefully try to clean this, as long as your instructor gives her or his approval.
Note how the sherd has broken, the orientation of inclusions and voids in the break, and any drag-marks on the interior and exterior surfaces that may signal the way the clay was manipulated during forming.
Turning the sherd under the light may also cast shadows that allow you to identify the flattened areas caused by paddle-and-anvil technique, or slight ridging from coiling (although this is a primary forming technique, it may have been disguised by paddling or trimming).

Vessel 6 is represented by three sherds, two of which are convex on their outer surfaces, while the third is concave.
A group of 52 sherds (collectively catalogued as 97-297) were found in unit 312/398, within a 10 cm thick horizon divided amongst Levels 6, 7 and 8.
These sherds have all been attributed to the same vessel, based on their shared provenience and similarities in colour and fabric.

 potsherd - Roman pottery - Scanning pottery sherds
The initial technique investigated (which had proved successful with the botanical images) was to place the sherd directly on the glass plate of the scanner and place a shallow box lid with a white interior over this.
The resulting image captures the essentials of the sherd, though it can be rather dark, particularly with larger sherds, and the background shows as a grey or brown colour.
The best sherds are clearly those that are both relatively shallow and flat, though sherds can also be propped on their edge to enable the break to be scanned.

Because this is so early, the sherd is a very important piece of evidence about the history of spinning and weaving in the northern Andes.
She took the sherd and all the different photographs and casts and studied them to see what she could tell about this ancient bit of cloth.
Well, because the sherd is so small we can't tell which is the warp (the vertical threads) and which the weft (the horizontal threads).

 Pottery Sherds
Pot sherds are important to the archaeologist because they are usually present in large numbers and are sensitive to both time and areal differences.
The pottery sherds display so many different characteristics such as the variations in color, thickness, hardness, tempering material, vessel form, decorative treatment, etc., that they are extremely useful to establish the general time period for the site where they were found.
Figure 45b is a rim sherd decorated with trailing and with triangular punctates produced with a small stick impressed into the clay at an angle.

Thirty-four (34) sherds were examined in order to see if there were any textural or mineralogical characteristics that would assist in the form and type separation of this pottery.
In general, the fiber voids which are oriented end-on (ovals in photomicrograph) are concentrated in the core of the sherd while the elongate fiber voids are found in the regions near both the interior and exterior surfaces.
Lastly, several sherds were observed to have infilling (or rimming) of the voids by calcite mineralization.

As you identify the types, weigh each sherd, test the hardness using the Mohs hardness kit and identify the vessel form represented by each sherd.
When assessing sherd hardness, be sure to scratch the cross-section of the sherd, not the surface.
Because your sample sizes are small, it might be that your samples match the frequencies of more than one midden, or they may not quite fit any midden.

 Results of the 'round robin' experiment
The observation that the two sherds yielded different results may be due to oxidation of the unsaturated fatty acids.
Laboratory j removed the outside surfaces of the sherd, to avoid possible contaminants, after which a total of 12 samples were obtained at evenly spaced intervals from the rim to the base of the vessel segment, six from the interior and six from the exterior.
Aliquots of the ceramic powder, weighing an average of 4.8 mg, were manually compressed in tin foil capsules and combusted in a Carlo Erba elemental analyzer interfaced with a MAT 252 isotope ratio mass spectrometer.
