Saving Pre columbian jar ecuador

This piece originally noted as from Panama, central America, veraguas

...however, I believe it to be from Ecuador, due to the shaping of the pot lip and proportions...Ecuador used sand to fill before firing, possibly making the darker crackling texture in the clay...

...also, pieces from Ecuador have been known to be traced far up northward, due to migrations...

...then the general circa 500 to 1000 ad probably in this scenario

...a red lip with sunrays coming down belly of jar

..an example of an unusual crinkle pattern in the glaze, indicating addition of a 'mineral' before firing...

...experimenting with added matter to inhibit breaking during firing

...17inches around belly...3 1/2 saving inches high and 4 1/2 inches diameter across mouth of jar...no repairs, original condition
