Featured a black pot and others

I know what 2 are, just adding them in, The tan colored pot is by Alabama Coushatta tribe which hails from Texas Dated1984. The little jug was the first NA I bought several years ago Iwas pleasantly surprised to see it is by a listed Pine Ridge potter, The black one has me stumped, I am unable to read the writing on the bottom, so any pointers will be very much appreciated.

 

look towards San Idlefonso Pueblo..and / or Santa Clara....

 

It appears to be Santa Clara.

Both San Ildefonso and Santa Clara potters make this type of pottery, which has to be fired traditionally in an outdoor bonfire to achieve the distinctive black color. It's a special type of oxygen-reduction where at a certain point, oxygen is not allowed to reach the pot, and a chemical reaction occurs that turns what would otherwise turn out to be red clay, to black.

It is more difficult, however, to make thin pots with Santa Clara clay, due to its composition. Santa Clara potters, therefore, often carve out designs, rather than using a slip to paint the designs on. Carving the designs reduces the weight of the pot, and also reduces the firing cracks sometimes encountered with thicker pots. (Information that came directly from a well-known Santa Clara potter.

The red, unglazed, pot also looks like it's Santa Clara. This is the color the black pot would have been, if fired differently.
