Agar is derived from red seaweed and is available as a powder that forms firm, translucent gels or films when heated with liquid and cooled. It is commonly used as a plant-based alternative to gelatin and functions as a bio-based and biodegradable hydrogel.
Handling Notes
- Versatile
- Mix powder (dry agar) with hot liquid, and it sets firm at room temperature—no refrigeration needed
- Reheat to reshape; adjust gel strength by varying concentration
- Often used as a composite or binding agent in biomaterials and DIY material making
