Prior to the arrival of the Spanish, Chinese settlers pioneered a still-active pottery industry. You can visit a couple of pottery factories on Gomez St. The 50m-long kiln at RG Jar, which was made in 1823 and can hold nearly 1000 jars, is a wonder to behold. Local potters let you create your own misshapen ceramics at the pottery wheel.
You can buy a small clay souvenir afterwards. The burnay (earthen jars) that you find here are used in the fermentation of ²ú²¹²õÃ (sugar cane wine) and bagoong (fish paste), but you are more likely to see them scattered about in homes and gardens.
