When I was staying in the city of Guanajuato, some potters were firing their stuff with used motor oil.
That is one fuel source that sounds good for intense heat needs. I had a friend that used motor oil for a foundry melt furnace years ago. You can tune in the flame after half a minute or so to a well balanced blue. If I were doing this, I would get the gadgets in the USA - blower, pyrometer, and any controls you wanted (if you want them). You would fast be popular in Mexico - heck, you'd be a celebrity in Oaxaca. I certainly would not lug dead weight bricks (kiln) to Mexico. You could construct an adobe kiln rapidly and cheaply to any size you like, but I would bring that old $25 kiln design book that is available in the USA. You could help save a lot of trees down here, improve the air quality a great deal, and raise the temperature beyond the wildest local dreams. Might help the lead glaze problem and increase durability.
Low temperature traditional wood fired kilns (in many cases little more than bonfires) are valuable for a few national treasure type artists cases and for the famous black pottery of San Bartolo Coyotepec.
You would be paying about 18 cents US a kilowatt for the electric energy you used in Mexico, and contributing nothing applicable to the technical knowledge base of the area.
Whoops! Gotta close the door, neighbors are burning their daily trash with plastic.
