Another year has passed and even though the project did not receive funding to continue major excavations, we are pleased to have received support for basic lab operations from the Office of the National Marine Sanctuary thanks to the efforts of Dave Alberg, Sanctuary Superintendent for the Monitor National Marine Sanctuary. This vital assistance, which was supplemented by additional funds from Friends of Queen Anne’s Revenge, Lauren Hermley, Executive Director, enabled conservators to continue making exciting discoveries in the lab. Since laboratory staff did not have to process artifacts coming in from the field, they were able to focus on learning more about artifacts already recovered from the site and gather additional information through different types of analysis. We were fortunate to have some crew members return, however we have also had some members of the team move on. Crew Member Moving On…..
On May 8th the QAR project said goodbye to a top-notch employee as Franklin H. Price began a new chapter in his life by accepting a permanent position with the State of Florida underwater archaeology division. Franklin first started on the QAR project as a volunteer at the lab in February 2004 and was a tremendous asset through his contributions both in the lab with the processing of the sluice sediment, as well as with all aspects in the field. It has been a pleasure to work alongside Franklin and we wish him well in his new position as senior archaeologist. Volunteers
Matt Thompson, who recently completed ECU’s Maritime Studies Program, volunteered at the lab for 2 weeks at the end of June. Matt is no stranger to the NC Underwater Archaeology Branch as he has worked with state archaeologists at Fort Fisher on many occasions. Jeff O’Neill, a first year graduate student in ECU’s Maritime Studies Program, volunteered his time at the QAR lab early in the fall semester. Jeff helped Lauren McMillan with ballast sample processing by recording weights and counts. The QAR staff appreciates the work of all volunteers and hopes to see the interest in the QAR project grow among ECU’s graduate students in all areas of study.
QAR Lab Crew Fall 2009 Myron and Lauren are rejoining the crew until May 2010 but Jon Schleier who has been with us since September 2007 will be moving on at the end of the year as he completes his master’s degree course work. Jon has been a tremendous help and we will miss his assistance and sense of humor around the lab. Hair/Fabric Conservation Hair Conservation Before any QAR hair could be conserved, various conservation procedures were tested to ensure the best conservation method was chosen. Several small samples of hair were used to test the following possible methods for drying and consolidation: 1) Air dry (Control)
Each sample was photographed, weighed, measured, and its visual appearance was noted both before and after conservation. The best method for conserving QAR hair was found to be, topically applying, or misting with a spray bottle, 5% PEG 400 in RO water and then placing the treated piece in the freezer at a temperature between 8 to 10 degrees Fahrenheit until hair was dry to the touch. This particular conservation method provided stability with little to no breakage to its structure, as well as giving it a natural appearance. With a conservation method chosen, nine hair fragments were conserved, as well as any tar associated with the hair fragments. This method has proved successful in conserving QAR hair for future viewing and study.
Fabric Conservation Having identified fibers and recorded textile information, and after various experiments using different chemical cleaning agents, consolidants, and drying methods, she concluded the most appropriate method for the QAR textiles was to immerse the textile fragments in a 5% PEG 400 in reverse osmosis (RO) water solution for one week and then place the fragments in a freezer to undergo sublimation. Also, if there were any iron staining within the textiles, she suggested immersing the textiles in a 2.5% oxalic acid in RO water for no more than 2 hours to remove any iron stains before continuing the conservation process.
Our goal this past summer was to finish what Adria started back in 2008. Adria analyzed and took meticulous notes on textiles QAR345.014 and QAR347.006, so these textile fragments were ready to move forward in the conservation process. QAR345.014 textile fragments appeared to have iron staining on the surface, so they were treated with 2.5% oxalic acid first. Both QAR345.014 and QAR347.006 were cleaned with a continuous wash of RO water to remove any loose sediment from the surface. Each textile fragment was immersed in a 5% PEG 400 solution for one week and then moved to the freezer at a temperature between 8 and 10 degrees Fahrenheit for about one week. When the textile fragment was dry to the touch, it was removed from the refrigerator freezer and analyzed for any shrinkage or distortion. Using this conservation method, a total of 18 textile fragments have been conserved. This conservation method for conserving QAR textiles will allow for future viewing and study. Cannon 15
X-Radiography Update
What’s first? All of our priority one artifacts have been x-rayed and we are presently working our way through the priority two concretions. At the lab we have currently x-rayed whole pewter plates, pewter plate fragments, the clyster syringe (see below), spoons, copper alloy objects, 1 wooden handle inlayed with pewter and 1 silver coin. Markings on some of the objects were visible but not discernable without radiography, however, the x-ray images helped to clarify these marks allowing them to be identified. This was the case for a maker’s mark found on a pewter plate that will be described in a comprehensive report about the pewter artifacts to be posted on our website soon. So what are we finding in concretion?
Survey Chain Tallies or Markers In 1997, one survey chain tally or marker (QAR217.000) was recovered from the site and it remained the lone tally for ten years. X-radiography of concretions recovered in 2007 and 2008 field investigations have yielded six more survey chain tallies; two are the same shape as the first and three other tally shapes have emerged. The Surveyor’s Historical Society describes a surveyor’s chain as sixty-six feet in length or 4 poles; it contained 100 links (each 7.92 inches long) connected each to each by two rings with a tally mark at the end of every ten links. The markers or tallies would have one, two, three or four notches (in our case lobes) as they marked ten, twenty, thirty and forty links from either end. The fiftieth link was the center of the chain and was marked with a round tally which meant that one chain had a total of nine markers with five different tally shapes.
We have currently identified seven survey chain link markers with four different tally shapes that were found in the stern and midship area of the vessel. The tally recovered in 1997 has two lobes, which most likely was used to mark the second ten-link increment; we have discovered two more tallies that are the exact same size and shape as QAR217.000. Concretion QAR2489.000 contains one marker that has three lobes and concretion QAR3038.0000 holds three chain link markers, one with one lobe and two round tallies. In every concretion containing a survey chain link marker, we have had evidence of the iron links and rings however these items are totally corroded and will be good candidates for casting to preserve their form. From the information gathered from x-rays and what has been learned from the Surveyor’s Historical Society, we can speculate that we have more than one surveyor’s chain because of the presence of the three two-lobed markers and two round tallies; each chain would have two two-lobed and one round tally. It is possible, however, that we could have half of a chain. Chains such as these were most likely to be used for terrestrial survey not navigating the ship and thus must have been someone’s personal possession. Breech Blocks or Swivel Gun Chambers
X-radiography has also revealed two very intriguing concretions shaped like large beer tankards or steins. The major objects within concretions QAR1445.000 & QAR1509.000 were identified as breech blocks or powder chambers for breech loading cannon. Breech-loading cannon were utilized throughout most of the 15th through the 17th centuries. Robert Smith describes wrought-iron swivel guns used up to the early 18th century with the most well-known examples from the Bronze Bell wreck off Tal-y-Bont in North Wales, which dates from c1710 (Smith, 2004). To date, all of the cannon observed, recorded, and/or recovered from the QAR wreck site are of the muzzle-loading variety, in which the powder charge and projectile(s) of choice were loaded from the muzzle end of the gun. Breech loaders were loaded just the opposite, through the open end of the breech. The ammunition in these guns might be a number of different projectiles including hail shot, fragments of iron or stone contained in a small cloth, leather bag or wooden lantern. The breech loaders from the Tal-y-Bont wreck were loaded with small fabric bags full of lead shot. Once the ammunition was in the barrel, the breech block would be inserted into its holder and a wedge hammered into place at the rear (Brown, 2009). The cannon would have been discharged by firing the vent or touch hole in the breech block much like the muzzle-loading versions.
A single gun could have had several chambers ready for use and the ability to fire rapidly made the “weapon par excellence for close range, anti personnel fire in much the same way that the machine gun has been used since the beginning of the 20th century” (Brown, 2009). The ‘stepped neck’ of a breech block would have been the portion of the chamber that would fit into the rear of the bore. A wrought iron wedge would lock the chamber in place. Concretions QAR1445.000 & QAR1509.000 were found adjacent to the cannon at the south end of the site and were about five feet apart. The distinct handles and ‘stepped necks’ of the chambers are evident in the x-rays. Ten feet away was concretion QAR1937.000, which holds what appears to be a wedge used with the breech blocks. The presence of two breech blocks in concretions suggests that this type of weapon was aboard Queen Anne’s Revenge when the ship ran aground, however their being there begs the question, where are the breech-loading cannon? Being that these were lighter swivel guns and situated on the upper works of the ship, it’s likely they were salvaged when QAR was abandoned (Brown, 2009). *Smith, Robert D.

Mystery Artifacts
QAR0097.000 is a cast iron object that highly resembles the size and shape of the mystery objects in concretion however we are still not sure of this object’s identity. It has been speculated that these are a type of projectile, or weights for trading goods. These objects were presented to the public in a presentation about the current x-radiography status at SHA in 2007 however no one offered any explanation as to the identity. So here’s another call for help - if any readers have a suggestion then we would love to hear from you.
Clyster Syringe
Clyster syringes were used to administer enemas, a liquid remedy, usually water, into the colon to help with symptoms of constipation and other stomach aches or ailments. These particular syringes were in common use during the 17th and 18th century due in part to its popularity with the French King Louis XIV (Gallici: 2006). Clyster syringes have been discovered on shipwrecks such as the Natiere 1 (1704), The Amsterdam (1749), and Conde de Tolosa (1724). Two marks became visible on the top part of clyster syringe (QAR1904.000) after cleaning was complete. Both marks were hard to interpret due to damage or wear, probably due to the post-wrecking environment. Philippe Boucaud, a leading expert in antique pewter, was contacted to help interpret the markings. With his knowledge of pewter marks, he was able to identify both marks as French, with one being a town mark and the other a maker’s mark. The analysis of our clyster syringe and its marks will result in an upcoming Technical Bulletin. We want to thank Philippe Boucaud for his invaluable assistance with these clyster syringe marks.
Nesting Weights Update
As expected, when QAR2590.006 was removed, there was an ‘8’ in the bottom of the master cup QAR2590.007. As luck would have it, the master cup also possesses a mark, ‘N’ dot ‘C’ with a fleur de lys over the letters. The ‘8’ appears to be stamped over another mark (which is the same “N” dot “C”). Opposite the ‘8’ is another lone fleur de lys and there is also a “<” symbol in the bottom of the cup. Our consultants are puzzled over our weights but agree that the weights were most likely manufactured in Nuremberg and adjusted in France.The particular weighing system to which these weights belonged is still up for debate and we hope to have a more comprehensive write up about all of the QAR weights compiled soon. We would like to thank all of the individuals who contributed opinions and helped us along this path. We thank Diana Crawforth-Hitchins and Aimé Pommier for their input and look forward to working with them in the future.
Condition Assessment of QAR Collection at NCMM On May 29th, June 3rd and June 8th conservation staff, assisted by ECU Physic’s professor John Kenney, checked artifacts with NCMM curator Darlene Perry and curator Wanda Stiles from the Museum of the Albemarle. On August 13th, QAR artifacts on loan to the Museum of History in Raleigh were examined with the assistance of MOH staff Matt Neal. Altogether about 62% of transferred artifacts were examined including all 4 cannon. Artifacts were visually inspected and assigned one of the following condition categories:
Over 90% of artifacts seen were in condition category A – which was good news! Of concern, however, was the active corrosion seen in all cannon bores, some (c. 6%) of the wrought iron nails and a few other wrought iron artifacts. These artifacts will either be retreated or, following discussion with museum staff, be subjected to a rigorous, localized control of the environment, particularly maintaining a relative humidity less than 20%, as a strategy for minimizing further corrosion. Providing a drier environment diminishes the rate iron corrodes. Artifact Transfer to NCMM
XRF Analysis So, what is this portable XRF? It is an instrument used to identify base elements in a substance and calculate the amount of those elements present in the artifact. Each element has specific characteristic x-ray emission, which can be measured by its intensity of its characteristic line. In October, the QAR conservation lab applied for and was awarded an academic research grant through Innov-X Systems, Inc to obtain a portable XRF. This resulted in the use of an Innov-X Systems Alpha Series Handheld XRF Analyzer for two months to conduct qualitative and quantitative elemental analysis on QAR artifacts. In return, we will submit our findings at a conference of our choice. Right now, we are in the process of testing artifacts and analyzing the data obtained from the XRF. We will up-date you on this project at a later date. *We want to thank the following: Public & Professional Outreach Lab Visitors
On November 6th conservators from the USS Monitor Project based at the Mariner's Museum in Newport News, VA visited. Former QAR lab staff, David Krop and Eric Nordgren brought their colleagues, Tina Gutshall, Elsa Sangouard, Will Hoffmann, Karen Heaton, Laura Reid, and Josiah Wagener for a tour of the facility just after lunch. Conservators compared notes on corrosion potential monitoring as well as wood and fabric conservation. We are fortunate to be able to consult with the Monitor conservators because they are dealing with many of the same conservation issues as the QAR lab.
Researcher visit
Public Displays
The North Carolina Maritime History Council held its annual meeting at the North Carolina Maritime Museum Sept 10th-12th. During the first afternoon of the conference, Friends of QAR director, Lauren Hermley organized a session where both archaeologists and conservators set up displays and were on hand to answer questions from the public.
Silk Hope Elementary School in Siler City was invaded by pirates on October 30th. Ms. Heather Rutherford and Mrs. Holly North’s fourth grade students dressed in pirate costumes as they enjoyed a day full of activities related to pirates in their study of North Carolina’s pirate history. Wendy started the day off by giving the fourth graders a presentation about the QAR project. Eighth graders were also given a presentation and their teacher, Mr. Durso, was so concerned about our lack of funding that his students wrote and mailed 48 letters to Speaker Hackney and Senator Atwater.Thank you for the support!!
On November 5th, Myron Rolston spoke to 24 students in Mrs. Larkin’s fourth grade class at Stokes Elementary in Pitt County. He discussed the significance of piracy to North Carolina, the history of Blackbeard, and the current work going on at the QAR Lab. ASK magazine is an arts and science magazine for children ages 7-10 issued by the same publishers of Cricket magazine. The November/December ASK issue is titled, “Searching for Pirate” and features an article about the occupation of an underwater archaeologist from the QAR project. For the months of November and December students can submit questions about the project at: http://www.askmagkids.com/asktell/ask-underwater-archaeologistAny comments, suggestions or questions can be directed to the conservation report editor at: wendy.welsh@ncdcr.gov Credits and Acknowledgements - Photographers include Wendy Welsh, Shanna Daniel, Franklin Price, NC Museum of History and John Kenney.
