Reconstructing Reconstructing Pots-Pots-Reconstructing Reconstructing Lives:Lives:Analysis and Reconstruction Analysis and Reconstruction of Ancient Ceramics from of Ancient Ceramics from EcuadorEcuador
Our PotteryOur Pottery
PurposePurpose
To analyze ceramics from To analyze ceramics from the Guangala civilization the Guangala civilization to determine the to determine the likelihood that chicha likelihood that chicha production, storage, and production, storage, and use were an integral part use were an integral part of daily life.of daily life.
To obtain a To obtain a representation of vessel representation of vessel types and sizes used for types and sizes used for chicha in prehistoric chicha in prehistoric Ecuadorian households.Ecuadorian households.
Chicha was a light alcoholic beverage
similar to beer that is currently consumed at festivals and in home
use.

Functional AnalysisFunctional Analysis
Three main sources of data were used Three main sources of data were used to determine vessel function:to determine vessel function:
1.1. Observations on ceramicsObservations on ceramicsMetric analysisMetric analysisTechnological analysisTechnological analysisUse wearUse wear
