Ingredients:
Water (75 mL).
Agar agar powder (3 g).
Glycerol (4 g).
Procedure:
Add all ingredients into a 500 mL autoclave bottle and shake thoroughly with lid closed.
Loosely open lid.
Microwave for 20 seconds on high with the goal of boiling the agar solution.
Take out of microwave and close lid.
Shake for one minute to dissolve.
Repeat last 4 steps 4 more times.
Once repeated 4 more times, cast into a mold (I used a 11.5 X 16.5 cm silicone mat).
Properties:
Before drying: bubbles on the surface and sort of looks liked diluted pee.
After drying: strong, smooth, and a less concerning color.
Notes:
Keep a good eye on the bioplastic while microwaving because it will boil over. When it boils over, stop the microwave and wait for a few seconds for it to calm down before continuing the microwaving.
A 125 mL bottle will boil over almost immediately. Trust me!
Because of the bubbles produced in the microwaving process, there were bubbles in my bioplastic. Besides that, the bioplastic is very smooth and has no imperfections.
This is the absolute best bioplastic yet by a land slide! Super smooth and consistent. It looks and feels like vinyl. Furthermore, it is very close to being fully transparent. I can't wait to modify this recipe!
