Agar-based ice gel forms when a 1.5–2 % agar solution is heated to 90–100 °C and cooled to 35–40 °C, creating a firm, transparent network that traps water.
Origin: East Asian (Traditional to modern) — East Asia
See full technique reference →The gelation mechanism involves the formation of agarose double helices that intertwine into a three‑dimensional network. Hydrogen bonding and van der Waals forces stabilize the structure, allowing the gel to remain solid at sub‑freezing temperatures. The process is reversible upon reheating above the melting point (~85 °C).
