In my previous post I made a case for the connection between the as yet unproven Salado white slip trade and the well established Mule Creek obsidian trade. In this post I will show the results of my hunt for the Salado white slip and make a connection between the best source I have found and the Salado trade network.
Let me begin by outlining the criteria for my search. I know other replicators who have used white slips from near but not in the Salado heartland but I am skeptical of these sources as possible candidates. It makes sense to me that Salado polychrome technology was invented by a potter who was experimenting with local materials, once the recipe was established, the technology and the slip material was disseminated outward from that location. Therefore it is highly unlikely that the source is on the periphery of the Salado phenomenon but more likely near the center of that movement.
I have been searching and sampling materials across the Salado heartland for years looking for a source of white smectite clay that will turn organic paint black. I searched all the highways and most of the back roads, then started using online satellite imagery to locate white colored minerals near Salado pueblos, then hiking out and sampling those. Most samples either 1) did not have the ability to turn organic paint black, 2) fired to an undesirable yellow or tan color or 3) were not clay but some other material (tuff, gypsum, etc). (Figure 1)
|Source description||Clay||Holds organic paint||Fired color|
|Cannonball Mesa, CO||YES||YES||WHITE|
|7 Mile Canyon Hwy 60 (north of Globe, AZ)||NO (probably gypsum)||–||–|
|Cañada Atravesada (near Reddington, AZ)||NO (probably welded tuff)||–||–|
|Lower Gila Box/Nichols Canyon, NM||NO (tuff)||–||–|
|Hwy 70, east of San Carlos, AZ||YES||YES||YELLOW|
|Benson, AZ||YES||YES (marginally)||WHITE|
|Mule Creek, NM||NO (welded tuff)||–||–|

Some of my best Salado polychrome replicas have been made using clay collect from Cannonball Mesa in southwest Colorado, this is obviously not in the Salado heartland, nor is it close enough to be reasonably considered something Salado potters had access to via trade. It is a clay slip that is commonly used by Anasazi pottery replicators and I use it as a control because it provides the results I am looking for and I compare all new slips I test to it. As you can see from the table, most local samples have been unacceptable in one way or another except the sample from Klondyke, Arizona.
The Klondyke clay was recently discovered (September 2015) and appears to provide the desired results (Figure 2) and looks very much like what is seen on Salado polychrome pottery. The source is only 3.5 miles from Haby Pueblo (BB:3:16), a large Salado site with a strong connection to the Mule Creek obsidian network with 64% of obsidian coming from Mule Creek (Neuzil 2008) and a high percentage of Gila Polychrome at 88% of total datable sherds, (Hartmann and Lee 2003) another large site nearby is Crescent Ruin (BB:8:6) about 8 miles away with an even larger percentage of Gila Polychrome at 87%, this site also has a strong connection to the Mule Creek obsidian trade with 71% of obsidian coming from Mule Creek. (Figure 4) Finally, the Klondike source is located close to the geographic center of the Salado phenomenon. (Figure 3)
After years of exploration and testing, I can at last say that I have found a suitable candidate clay from within the Salado heartland. My tests are ongoing, and more information will be made available here on this website as it becomes available. I would be interested in talking to anyone who can provide chemical tests of my slip against Salado polychrome sherds for a definitive conclusion.
|Site Name||Site Number||Approx. Distance to White Clay||% Mule Creek Obsidian||% Salado polychrome|
|Haby Pueblo||BB:3:16||3.5 Miles||64% (Neuzil)||88% (Hartmann)|
|Crescent Ruin||BB:8:6||8 Miles||71% (Neuzil)||87% (Neuzil)|
|Eagle Pass Ruin||BB:4:1||4 Miles||0% (Neuzil)||90% (Neuzil)|
