Sudsud (Plowpoint) at Lipya (Plowshare) are the most important parts of The Plow (see image), an indispensable tool of a farmer. Until early 1990s, Angat was the acclaimed source of these parts mainly because their design functionality and durability.
Made of white cast iron, Sudsud and Lipya were manufactured by directly converting Iron (Fe) ore in low-shaft furnace using hardwood charcoal as reducing agent.
Popularly known as Tatak “A”, the Made in Angat Sudsud at Lipya, are produced using the following major raw materials which are indigenous to our town:
- Iron Ore (Hematite) is from mines in Sierra Madre Mountain which was part of Angat in those days.
- Charcoal is used as the equivalent of Coal in a regular blast furnace operation. It is made from local hardwood like Kamatsile and Sampalok.
- Silica Sand is the material used for the moulds for the Sudsud at Lipya which can be hauled from the banks of Angat River in the old days.
- Bentonite is the sticky clay material that binds the silica sand to form the moulds of Sudsud at Lipya.
The Sudsud at Lipya are testaments to the ingenuity of the older generation of Angateños who made us proud for having supplied the nation with these components of the necessary tool for agriculture. The items provided for the livelihood of early farmers and though they may have been made obsolete by modern farm machines, Sudsud at Lipya should remain as part of our culture as proud citizens of Angat.
