Agar Ag14 (2mm Film, without Plasticizer)

Fail

^ The pink came from the sticky note I stupidly placed on top of it!

Ingredients:

• Water (50 mL)

• Agar agar powder (2 g)

Procedure:

• Mix all the ingredients into a pan or pot

• Heat up all the ingredients to 85-90 C on the stove

• Mix thoroughly

• Lower heat if bubbles are forming on the bottom of the pan

• Take off heat after about 4 minutes of stirring or until the agar is fully dissolved (the solution is at least 85 C and thicker than when started)

• Let dry for a few days on silicone. Remember to pour it in a thin-ish (2mm) film.

• Done!

Properties:

• Before drying: very viscous and brown

• After drying: hard, but brittle "film"

Notes:

• Final thickness: 0.5

• I also poured some in like a 3-5mm film to see if it became sort of leathery (it still hasn't dried)

• I think I used way too much agar to make a film

• It spilt apart when it dried, causing it to fracture and break itself. I presume this is because of the lack of plasticizer.

• No flexibility

• Severe warping

• Brittle

• Moral of the story is to always use plasticizer!
