# 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! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
