This page describes some of the basic tools that are used during
the preparation of reports on archaeological ceramics. Some
relevant web links are included. The topics covered are:
A binocular microscope is an essential tool for the detailed
examination of pottery fabrics and identification of
inclusions. For ceramics work a long arm stand is essential when
viewing large sherds or complete vessels. Most have
interchangeable lenses from x10 to x35.
For `field' use a small hand lens is invaluable.
The colour of pottery fabrics are conventionaly described by
reference to a colour chart, such as the Munsell Soil Color
Chart. The Munsell notation (e.g. 2.5YR 6/4) is commonly found
in fabric descriptions in published pottery reports.
There are numerous web links describing the Munsell Color
system, often as part of teaching notes for courses on color
perception and similar topics. The Adobe web site includes a
technical
guide to the Munsell system, and information on
other color models.
In Britain, the soil color chart can be obtained from D.G.Colour Ltd, whose
website also includes a short summary of the Munsell
system.
The EasyRGB site
includes an online colour
calculator allowing conversion between RGB values and
Munsell colour codes. Of course, most terminals are
incapable of this sort of
precision.
A rim chart (or radius chart) is needed to measure both the vessel
radius and the proportion of the rim represented by a sherd when
collecting vessel equivalent statistics.
Click on the thumbnail images to download PDF files (size
18k-20k) for printing the rim charts on A4 paper.
If you do not
already have a PDF reader
browser plugin installed, the file can be saved on
disk.
Some printers do not print images at a precise scale, so make
sure that 10cm on the paper does actually match 10cm on the
chart.
Initial recording will usually take place on a paper recording
form, tailored to the particular requirements of the project,
the recording techniques employed and the final destination of
the records.
