Overview
A classic hand-coiled 'barro negro' (black clay) pottery vase featuring a globular body and a flared rim. This piece bears the hand-incised signature of Doña Rosa Real de Nieto, the legendary artisan who revolutionized Oaxacan black pottery.
Story
In the 1950s, a Zapotec potter named Doña Rosa made a mistake that changed art history. By rubbing the drying clay with a quartz stone and firing it at a lower temperature, she turned dull gray clay into a metallic, obsidian-like treasure.
Maker / Origin
Doña Rosa Real de Nieto (d. 1980) is the most famous name in Mexican black pottery. Working from her home studio in San Bartolo Coyotepec, she hosted international presidents and artists, single-handedly turning her village into a global destination for collectors. Her family continues her workshop and signature style to this day.
Condition & Value
The vase appears to be in good vintage condition with minor surface scuffs and light scratches consistent with age and handling. Because barro negro is fired at a lower temperature to preserve the shine, it is fragile and prone to chipping; luckily, this example shows no major structural damage.
