# Agar Ag12 (4.5mm Film, with Plasticizer)

![](/files/o8WrUERu8LsEqwHhKJGx)

Ingredients:&#x20;

* Water (75 mL)
* Agar agar powder (3 g)
* Glycerol (4.4 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 or something similar. I used an 11.5 X 16.5 cm silicone mat. When poured onto my mat, it naturally reached all four corners and was about 4.5mm thick.&#x20;
* Done!

Properties:

* Before drying: very viscous and brown&#x20;
* After drying: a thicker film that's super strong!

Notes:

* Final thickness: 0.5mm (it shrunk about 9 times in thickness!)
* Varied casting thickness
* It's really hard to measure the casting thickness, so I'm going to note it could have been between 3.5-5mm.&#x20;
* Super strong
* Translucent
* Flexible
* Best film yet!
* Oh my goodness this takes forever to dry!
