Saf Su (Pure or Distilled Water) at Gordion

Our goal: obtaining saf su.

Distilled or deionized water is important in many treatments completed here at Gordion Excavations. Therefore, one of our first and top priorities is obtaining an appropriate source of water, which proved to be quite a challenge this season. We first attempted the deionizing columns left over from previous years, but after several rounds the conductivity of the resulting water was off the charts.

Discussing the deionizing column with a chemical salesman in Ankara.

During a trip to Ankara, we ventured on a mission to find a local source for purchasing deionizing columns. The set up for purchasing chemicals and supplies in Ankara is rather amusing. In one section of town, there are a few strip malls with stores that sell medical, laboratory, and chemical supplies. In many ways, the experience feels like purchasing a car. The chemical salespeople contemplated the column: they tapped it, shook it, sniffed it, then called in reinforcement, who also tapped it, shook it, and sniffed it. After several visits to different stores, many confused looks, and a few phone calls, we were unsuccessful in locating a column.

Defeated in our quest for a deionizing column, we set up the still back at the lab. Although the process is slow, after several days of running the still, we were able to obtain enough distilled water for the season. In case we run out, several small bottles of distilled water were purchased from a petrol station in Polatli, a nearby town.

Feeling sorry for the water-deprived objects conservators, Gordion
archaeologists purchased these cute little bottles of distilled water.

Perhaps next season will be more successful in the quest for purchasing a deionizing column in Turkey - a tip from an Ankara local suggested home improvement stores that may carry water filtration systems designed for the home.

With saf su in hand, Gordion objects conservators commenced with desalination and other treatments involving water.

  1. Nice post. Too bad you could not find any deionizing column in this part of Turkey.
    Maybe next time more luck. Ps what do you need the distilled water for?

  2. Thanks for your comment. I see you share an interest in distilled water :).

    The salt ions found in many water sources can be destructive to porous art objects, such as stone and ceramics. Several conservation treatments of archaeological artifacts, such as cleaning, require water. Conservators prefer to use deionized or distilled water to avoid introducing potentially harmful salt ions to the artifacts.

  3. I agree with you. Thank you for sharing the update. It is interesting to have it discussed widely so that we can gain more objective opinions.

  4. Fearing on your family’s well being since regular faucet water isn’t risk-free or even since well/spring drinking water every bit as is usually risky, it can be time period you study distilling drinking water within a container using some the rocks.
