DocuSign Envelope ID: 16F7E188 -42F5- 4144- AF1B- 934E4ACOFE59 <br />2. Artifact Tags <br />A tag replicating what is written on each bag should be laser - printed or written in <br />permanent ink on an acid -free paper. These tags should be inserted into each bag with <br />the text -side clearly visible upon bag closure. <br />The acid -free paper tag does not need to be bagged separately and can come into contact <br />with the curated artifacts in the bag, with the exception of materials that may render the <br />tag illegible, such as carbonized plant materials and metal artifacts. In such cases the tag <br />should be placed into its own unlabeled bag. <br />3. Fragile Specimens <br />Fragile items (bone, wood, shell, etc.) should be wrapped in acid -free tissue paper and <br />bagged, boxed, or placed in vials. <br />Use roll Styrofoam (1 /32" thick) or bubble wrap to package large fragile items. These <br />products are available in multiple widths. Do not use newspaper. It is highly acidic and <br />unstable and will not be accepted. <br />To pack fragile items within standard boxes, place Styrofoam peanuts or shredded acid - <br />free paper at the bottom, to act as a buffer and reduce excess volume. Do not use <br />newspaper. Place materials in position, then fill the remaining volume with Styrofoam <br />peanuts to keep the materials in an upright or stable position within the exterior storage <br />box. <br />Ethnobotanical or radiocarbon samples may not be placed in the same exterior boxes <br />with stone or ceramic artifacts. Sample- specific identifiers should indicate the nature of <br />the contents (e.g., wood, charcoal, carbonized seeds, etc.). All C -14 samples should be <br />packaged and labeled in the same manner in which they would be sent to a C -14 <br />laboratory. <br />Mounted microscope slides should be stored in an acid -free cardboard archival box or <br />sleeve. Each slide should be numbered, and the associated catalog number and other <br />relevant contextual information associated with each slide number written in permanent <br />ink on the container. The box or sleeve should itself be bagged and labeled according to <br />the information in the `Artifact Bags' and `Artifact Tags' sections above. <br />4. Metal Artifacts <br />Silica gel should be included as a desiccant if plastic bags are used for the storage of <br />metal artifacts, but the silica gel must not come in contact with artifact surfaces. <br />Fine or delicate metal artifacts may be stored in small plastic boxes or vials. <br />A small, perforated plastic bag of silica gel should be placed in each artifact bag or <br />container holding metal. <br />5. Soil Samples <br />Soil samples intended for flotation will not be accepted for curation. Flotation samples <br />should be processed and their contents treated according to the standards provided <br />above. Only soil samples taken to allow for chemical, pollen, phytolith, or similar <br />analyses will be curated.
