Object before treatment.
A copper dish coated with tin had dirt and residues of food on the surface.
Mechanical cleaning under the microscope.
I used mechanical cleaning to remove the dust from the surface under the microscope. After that I used calcium carbonate and water on cotton swabs for cleaning.

This pottery jar with a spherical shape has a circular base and brown stripes on the body (registration number IM222239 – Iraqi Museum). I worked on testing for soluble salt by using distilled water after taking a sample from the jar. I put on the sample a drop of nitric acid, then a drop of silver nitrate. The result was positive so the jar contains chloride salt.

When a new textile comes into the museum, it needs to be examined before storing it. For that we need to follow these steps:
- The textile is placed on a table and examined thoroughly in search of anything that might damage it.
- Remove any material on the piece like unconnected threads, dirt and dust.
- If there are insect holes in the textile or insects or eggs, we put the textile through a freezing or heating procedure to kill live insects.
- At the Institute, the textile is kept in the freezer for two weeks then checked again for insects.
- After the elimination of insects, the textile is ready to be stored.

Choosing a spot to test on an ancient pottery artifact.
Test for nitrates (NO3) soluble salt
- Nitrate test paper
- Distilled water
I put two drops of distilled water on the jar and then put the test strip (nitrate test paper) on the jar and held it there for about a minute. The color changing means that there are nitrates in the jar.
The test strip shows a negative result.

Examining the artifact
Examining an archaeological artifact under the microscope for inspection to study its condition. Is it deteriorated or not ? Has it it reacted with the surrounding environment or with other substances or not? We also investigate the materials of the artifact this way.
Documenting the observations

Documentation photograph before treatment. Note the label, scale and color card.
Photography of the object (before, during and after treatment). This kind of documentation serves as a visible record and also to show the materials and the techniques used for conservation
Treating the artifact.
Artifact during treatment.
It will also be of a great value to those who will come later to examine or work on the object
The photos can also be used to compare the objects we worked on with photos of other objects that suffer from similar problems
After treatment, front of the object.
After treatment photograph, reverse of the object.

At the beginning of the second module of the conservation course which started in March, and after our first home practicum projects had been discussed, then one of the advisory council members, Lois Olcott Price visited the institute and gave us some information about the Winterthur museum where she works and talked also about her job there. Later, Miss Jessie Johnson, Academic Director, brought us happy news about a trip to Sulaymaniyah to visit the exhibition which was sponsored by UNESCO in the museum of Slemani.
The next day we went there, the weather was wonderful and the trip was interesting especially with the presence of Miss Jessie and Lois .
The Museum was beautiful and attractive, the pattern of the exhibition was different and there were different kinds of artifacts. The subject of the exhibition was “IN WRITING”. After we finished our tour in the museum we took this beautiful picture together. Then we went to a restaurant for lunch with Jessie and Lois. It was very delicious. After lunch we came back to Erbil and the next day we discussed what we had seen in the museum.

Photographing a textile.
Photographing a textile. Because of its flat surface (as teacher Sebastian taught us) it was necessary to take the photo from above, with the use of light and arranging the camera on the stand and balancing it to have the best position to take a photo of this piece.

A good way to hang a textile on the wall is by using Velcro. Here is how it works:
1. Sew the Velcro to the textile. Put the soft part on the back of textile and the hard part on the piece of wood.

2. Put the wood on the wall with screws to make it fixed and stable.

3. Hang the textile on the wood that is on the wall.

Checking to make sure everything is straight, smooth and secure.
