Agar Ag15 (3mm Film, with Plasticizer)

Pretty much Ag12, but thinner

Ingredients:

• Water (60 mL)

• Agar agar powder (2.5 g)

• Glycerol (3.5)

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 silicone mat. When poured onto my mat, it naturally reached all four corners and was about 3mm thick, though you might need to manipulate it.

• Done!

Properties:

• Before drying: very viscous and brown

• After drying: thick and less strong than Ag12

Notes:

• Same recipe as Ag12 with the same ingredient ratio because I'm trying to find the best casting thickness.

• Interestingly, at least from just holding the bioplastic in my hand, it seems to be thicker than Ag12. This wouldn't make sense though because of the above statement.

• Also, oddly, it seems to be much more translucent than Ag11. You can barely see through it. I wonder why this is, and I wish I had taken a greater number of notes so I could have studied it.

• Very weak compared to the Ag12

• Elastic
