Answer:Burnay are earthen jars with small openings while those with bigger mouths are called wangging. In the early years, the burnay, locally known as tapayan or banga, was used for storage of water, rice grains, basi (sugarcane wine) and condiments like salt and bagoong (fish paste). Burnay jars are also used in the fermentation of vinegar that comes from the sweet sap of the Arenga Pinnata, a sugar palm tree more commonly known as “kaong.” According to locals, Arengga vinegar tastes better if stored in burnay jars than in plastic or metal containers
