Treatment Measures <br />A statement indicating whether conservation treatment was performed, and a list of objects <br />with a description of their treatments should accompany collections. <br />If conservation has not been completed, provide an itemized list of those objects needing <br />treatment. Cost of treatment will be determined on a case -by -case basis. <br />IV. Artifact Processing and Packaging <br />The OSA requires that materials submitted for curation meet certain general conditions prior to <br />acceptance, as outlined below: <br />a. Cleaning <br />All artifacts should be cleaned and stabilized prior to shipment to the OSA, except in <br />instances where an uncleaned condition would facilitate a particular form of analysis, or <br />where the depositor desires to have the OSA staff perform - -at cost -- cleaning, conservation, <br />packaging, and other tasks. <br />Artifacts should be cleaned with water or dry brushed. Wash only those materials that will <br />not deteriorate or where cleaning with water will not destroy archaeological evidence (e.g., <br />carbon deposits, slip on pot sherds, etc.). <br />Artifacts, specimens, or samples that require special care (i.e., those which must not be <br />washed or otherwise cleaned or processed) should be clearly separated from other materials <br />and marked: SPECIAL TREATMENT REQUIRED. <br />b. Sorting and Cataloging <br />A standardized method of collections - cataloging must be employed for each collection and <br />project. Include a full, written explanation of the cataloging method employed with each <br />collection. The cataloging system described below is recommended, but not required by the <br />OSA Laboratory Supervisor. <br />The formerly recommended cataloging system consisted of letters designating the artifact <br />class (e.g. p for pottery, b for bone, eb for ethnobotanical materials) followed by a sequential <br />specimen number unique to that catalog entry (1, 2, 3, 4, 5...). For collections that are the <br />result of Phase I surveys, it is not necessary to assign artifact class letters or unique specimen <br />numbers in this manner; designating artifacts by their 12 -digit catalog number (provenience <br />number appended to accession number) is sufficient. Artifact catalogs for these collections <br />should be sorted by site number, provenience number, and then material type. See <br />Inventories and Lists section below for information on how artifact catalogs should be <br />submitted to the OSARC, and `Packaging' section below for information on how artifacts <br />should be bagged. <br />In cases where only a sample of the recovered material is analyzed in detail, the analyzed and <br />unanalyzed materials should be separated and labeled accordingly. <br />North Carolina Oce of State Archaeology — Archaeological Investigation Standard and Guidelines December 2017) Page 32 <br />
