# Tools and Materials

### Basic tools and requirements: 

* Scale (at 0.1g resolution is recommended).
* Spatula.
* Nonstick pan or pot.
* Ice cube tray as a mold or a silicone tray for casting.
* Stovetop.
* Popsicle sticks for stirring and spreading.
* Mixing apparatus w/ measurement tools.

### Advanced Tools:

* Beakers (Pyrex works well).
* A 0.01g resolution scale is really useful.
* IR thermometer to measure bioplastic temperature.
* Work surface.
* Spreading apparatus of some sort. DIY it like it did for a fun weekend project.

### Ingredients:

* Water.
* Glycerol (50 - 100g bottle).
* Agar (50 - 100g).
* Carrageenan (25g).
* Sea moss.

### Home-made Tools

**DIY Injection Press v1:**

This was an experiment to see if I could sort of injection mold the bioplastic that's fresh off the oven. The main goal was to see if I put more plastic than would fit, and applied lots of pressure with a clamp, then hopefully the bioplastic wouldn't shrink as much. The problem I encountered was that it didn't dry in the chamber and shrunk later. I 3D printed it. I think making it metal and drying it in the oven would be the best approach, but I don't have enough money to CNC it. However, I don't think the concept is solid either.

**Tube Mold:**

There isn't much to this one. I got a plastic tube, 10mm in diameter and 220mm in length, and cut a hole for it inside a chunk of wood. To aid in pouring the bioplastic in, I implemented a funnel. The funnel is practically essential, though you might be able to make do in a pinch without it. Other options for the tube include straws and pen casings.
