# 12&13 - Project Bioplastic Consumables

## Week 12

### Testing with clay

At first I thought I had to make a mold and that the ultimate tool for making a mold at home is clay. So I started shaping my clay and made a mold with a cutting board.

But I soon figured out that pouring the cooking hot bioplastics in the clay mold didn't work.

The two clay molds melted immediatly and became really soft. The clay also affects the bioplastic. It makes it shrink more and a bit white.

**So for my experience the clay mold is a no-go.**

## **Week 13**

### **Gelatine Mold**

So I tried to make a mold out of gelatine Bioplastics. But the outcome was not what I expected it to be. When I removed the cutting board from the gelatine bioplastic I ruined the form of the mold, so that didn't worked out as well.

### Recipes

I also tried my first recipe.

![Flexible Bio foil test](https://2472482582-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LzaCPWnWmmX17D0w0O3%2F-M7w-DkyzOc4u8plGCR0%2F-M7w14POPwiRCyNRpALW%2Fweek1213molds_kimsinke_minormakerslab20201.jpg?alt=media\&token=fdf16cfa-bbd7-4798-ab39-c7773159e2ce)

The thin layer of the agar Bio foil really worked out great, but in a thicker form of the Bioplastic will create some gray on the top. I think that result appears because of the moisture content of  the recipe.

![Gray after one week](https://2472482582-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LzaCPWnWmmX17D0w0O3%2F-M7w-DkyzOc4u8plGCR0%2F-M7w1_wSI31eW96BUVk-%2Fweek14_kimsinke_minormakerslab20207.jpg?alt=media\&token=a8e9e01d-7e13-4d9d-b511-ad25bdb5521e)

The thin layer of the first Bio foil seemed great, but it was really sticky and fragile.

![Fragile and sticky first attempt](https://2472482582-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LzaCPWnWmmX17D0w0O3%2F-M7w-DkyzOc4u8plGCR0%2F-M7w32oQAWD9x50a6RXT%2Fweek1213_firstbiofoil_kimsinke_minormakerslab.jpeg?alt=media\&token=427df7ea-ab26-4904-aeb4-1a22bba93365)

I'll try to work with less glycerine from now on, so the materials won't become so sticky. And I won't use a vaseline underground.
