Clay Tablet Gets Custom Box

Tuesday, November 12, 2013
Submitted by Bill Voss

Clay TabletThis neo-Sumerian clay tablet, recording the sacrifice of a kid goat dates to ca. 2050 B.C. and is frequently shown to students as an early example of writing in cuneiform accompanied by the impression of a cylinder seal. Due to its frequent use it was decided to create a custom box which would keep the object secure and viewable behind a small window, but which also has the option of being further opened to allow the object to be removed from the enclosure. The tablet rests in a fitted recess in a block of ethafoam covered with cotton and hollytex (spun polyester) and can be seen through a window of polyester sheeting. To remove the object a flap secured by embedded magnets is lifted revealing the tablet as well as a second recess containing a pair of cotton gloves for safe handling.

Testing for Mold

Testing for Mold

We had a very busy day at the Cultural Recovery Center in Brooklyn. The volunteer paintings conservator examined a couple of paintings that an artist brought in during the morning, just before noon she removed an artwork from a frame and examined the piece for mold and damage, in the afternoon she examined art on canvas and tested for mold.

Salvaging Artists’ Works After Hurricane Sandy

Thursday, February 7, 2013

Rack of artwork with plastic protective coverA couple years ago, I received training so I could become part of a national cultural disaster response team called AIC-CERT (American Institute for Conservation Collections Emergency Response Team). After Hurricane Sandy, AIC (American Institute for Conservation) and the Foundation of the American Institute for Conservation established a Cultural Recovery Center (CRC) in Brooklyn to reach out to artists and owners affected by Hurricane Sandy. Each week one AIC-CERT member acts as the team leader assisting where needed. At the end of the week, the baton is passed on to another AIC-CERT member. I’m acting as the AIC-CERT team leader for the rest of this week and then all of next week.

Today I worked with a paintings conservator and an artist to review his paintings that had been stablized and lightly cleaned in the CRC studio by volunteer conservators during the past few days. I photo documented each painting, taking a picture of the assigned number to the painting, a front image, and any problem areas. The conservator discussed the damage and possible solutions for each painting with the artist. She will add her observations and recommendations to a treatment sheet that is kept for each painting.

We then set each painting into a wooden rack that a volunteer had constructed for safe keeping until the artist can pick up the paintings.

Record Return!

Preparing to move all 30 boxes on a cart.

Preparing to move all 30 boxes of clean records.

We have been working on many projects for various museums that got hit by the flood of 2008. Remember the entry way back on December 18 of 2009? We may have sounded elated about our accomplishments then, but now we are for sure! We have finally finished the rest of the flood-damaged phonograph records.

Cleaning Busts

Thursday, February 11, 2010

Blog IMG_0920One project that Kallie is working on is cleaning a collection of busts. After Caitlin tested a couple different treatment methods she settled on using a mixture of water and photo flo roughly a 4:1 ratio. Kallie has been using swabs and cotton pads to remove the mud covering the busts. This process is particularly time consuming due to all the small crevices in the sculptures. There are 7 busts and Kallie has completed one and is halfway finished with a second.

The busts were a part of The Old Taylor Distillery Blog IMG_0922Company bourbon whisky promotion. For $5 you could buy a sculptured bust of an ingenious American. They belonged to Mrs. Gerolyn Banks, a teacher who used them as instructional tools in her classroom (incidentally, she didn’t drink alcohol). Kallie is working on Lewis Latimer who worked with Thomas Edison and developed an improved method for the production of carbon filaments in Edison’s light bulb. The ad for this particular bust can be found in Ebony, July 1967.

Other busts in the series include: Granville T. Woods who improved telegraph system for railroads; Garrett Morgan who invented the electric traffic signal; Benjamin Banneker was an astronomer, clockmaker, and surveyor who predicted eclipses; Norbert Rillieux improved sugar refining process; and Matthew Alexander Henson reached the North Pole with Admiral Peary in 1909. He was actually the first member of the team to set foot on the spot.

Two Vernons and a Typewriter

Monday, January 4, 2010

Blog IMG_0087

One of our quandaries was how to clean Vernon Smith’s typewriter, an important artifact from the African American Museum. We found our answer when we contacted Vernon Steve at Steve’s Business Machines (formerly Steve’s Typewriter) in Iowa City. Vern cleaned and repaired the typewriter but did not repaint it. The typewriter shows the wear and tear of the flood but is clean and fully functional.

Vern inherited the business from his father. He not only repairs typewriters but also repairs cash registers, old calculating machines, time-clocks, etc. In fact, after seeing the results of the typewriter cleaning, we left a flood-damaged sweeper for repair.

The typewriter was a college graduation gift from Elmer Sr and Vesta Smith to their son, Vernon. He graduated from Coe College circa 1950. He used this typewriter to type up his master’s thesis at the University of Iowa. He received a master’s in Chemistry from the U of I in 1952. Before receiving his master’s he had accepted a position as a chemistry instructor at an African American college in Virginia. 10 days after receiving his master’s while he was packing to move to Virginia, he contracted polio and lost the use of both of his legs and one of his arms.

He spent 4 years recovering from polio and then found a job in the special laboratory at St. Luke’s Hospital in Cedar Rapids. He worked there for 35 years retiring as head of the lab. He was very active in community affairs in Cedar Rapids, particularly in Civil Rights issues. He co-founded the Cedar Rapids Negro Civic Organization in 1961 and served on its scholarship committee throughout the 1960s. In addition, he served as a member of the Cedar Rapids N.A.A.C.P. and the Cedar Rapids Council on Human Relations. In 1971, he was named “Handicapped Iowan of the Year”. He married Phoebe Downs and raised five children: Ruby, Vernon, Deborah, Phoebe, and Katharine. He passed away in 2000.

Czech Pipe

Tuesday, December 15, 2009

Blog IMG_0564This carved wooden pipe from the Czech Slovak Museum was covered in mud and dust. Since it has so many small crevices it was very hard to clean. I used dampened swabs to remove the dirt. It is in three pieces and combined it took 6 hours to clean.

Below is the before (left) and after (right) cleaning of the pipe stem.

Suitcase Saga Part 4: Conclusion

Thursday, December 12, 2009

After lots of fussing and fiddling the suitcase is finally done. I removed all the rust from the exterior and cleaned up the metal. The interior was trickier. I removed the paper lining and lined it with a heavy japanese paper and wheat starch paste. Underneath the paper the metal of the suitcase was extremely rusty so I removed that rust as well before re-adhering the new “lined lining”.  It wasn’t possible to remove the mold stains from the paper lining so this suitcase has ended up with a much more colorful interior than it ever had in it’s pre-flood life!

Steve Stenstrom Workshop on Shellac Finishes

Tuesday, November 10, 2009

Blog shellac 004Steve Stenstrom returned to the UI to teach us about Shellac. We learned about the properties of Shellac and the different ways to use it. Steve brought us pieces of wood to work with and we all got some experience “french polishing” which consists of a cotton pad soaked in Shellac wrapped in a piece of cotton (old tshirts work the best). Using the pads we learned the basic technique for finishing a piece of wood with shellac. This will mainly be applied to the trophies and plaques we have from the African American Museum.

Read “The Story of Shellac” and learn how insects make shellac.

Storage is as important as treatment

Wednesday, October 7, 2009

dessicant bagThe objects we have received since the flood span a wide range of materials. Since we couldn’t work on everything immediately, one of the first things we had to address was proper storage. The wooden objects were set out to dry as were the baskets and miscellaneous plastic, ceramic, glass items. The metals however presented a problem. They were rusting and since we weren’t able to get to them immediately we needed to arrest the deterioration somehow.

After doing some research and consulting with Steve Stenstrom, an objects conservator, we bought large plastic tubs in which we could create a micro-environment for the metal objects. This allowed us more control over the condition of their surroundings. We put packages of plastic tub with metal objects and dessicants dessicant in the tubs with the metals to absorb any moisture which might contribute to the deterioration of the metal. The dessicant packets were switched out periodically and we were able to slow the process of rusting until we had a chance to stabilize the objects.

The items in the tub to the left are already cleaned and waiting to go back home to the African American Museum of Iowa.
