Pre-Spanish Era

• The first inhabitants in the archipelago who settled in Palawan and Batangas around 40,000 years ago have made simple tools and weapons of stone which eventually developed techniques for sawing, drilling, and polishing hard stones.
• They have come to understand that when clay is mixed with water and then shaped into something before sun drying, it hardens to an object that can also be useful to them.
• As the early Filipinos flourished, they have learned how to extract, smelt, and refine metals like copper, gold, bronze, and iron from nature and consequently fashion them into tools and implements.
