# Agar Ag12 (4.5mm Film, with Plasticizer)

![](https://829019481-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FQKxP3dLVX23EmnpaB5PS%2Fuploads%2Fe7sqKRb0Cn50BX8IyOy0%2FIMG_2215.jpeg?alt=media\&token=8e5873f8-294b-46e8-b02f-48f7a5d0375d)

Ingredients: 

* 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. 
* Done!

Properties:

* Before drying: very viscous and brown 
* 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. 
* Super strong
* Translucent
* Flexible
* Best film yet!
* Oh my goodness this takes forever to dry!
