Knotpot is a product of Knotfactory, next to Knotplex.

Testing knotpot recipes[edit | edit source]

The knotpot is a small cultivation pot designed for agriculture to dissolve in a couple of days. Due to this requirement we want to use only biodegradable materials. These pots are bigger than ø 6 cm. The knotpot is currently only made out of the Japanese Knotweed, water and hide glue, but can vary through these testings.

We are also looking towards other settings; such as adding temperature, other materials which can be used as a binder.

TP1: the first knotpot result

This pot represents the first test result with a new mold, specifically designed for cultivation purposes. We used the recipe from the Knotplex. Yet, this proportion between the glue and the fibers is too liquid. From our previous test, we discovered that protein could be a valuable additive.


INGREDIENTS
20 g Japanese knotweed
16 ml water
16 g hide glue
20 g rice protein

SETTINGS
10 ft
20 minutes pressing time

STEPS
1° Heat the glue granules until it completely absorbs the water and has a sticky, homogeneous texture.
2° Measure the fibers and protein and add them to the hot glue.
3° Put it in the mold and press it like described in the setting.
4° After the pressing time, take the pot carefully out of the mold.

ANALYSIS

Pros Cons
The first cultivation pot The bottom was dry: the glue raised to border of the pot
The pot came out the mold in one piece Not enough material



LEARNING LESSON
Because we hadn’t had enough material, the pot came out half. So the next test must have a better mixture and maybe more material.



N° 2[edit | edit source]

The second result with an adjusted recipe

The second pot is slightly different from the first version. We used more JKW fibers, water and more protein.

INGREDIENTS
70 g Japanese knotweed
190 ml water
110 g hide glue
40 g pea protein

SETTINGS
10 ft
20 minutes pressing time
STEPS
1° Heat the glue granules until it completely absorbs the water and has a sticky, homogeneous texture.
2° Measure the fibers and protein and add them to the hot glue.
3° Put it in the mold and press it like described in the setting.
4° After the pressing time, take the pot carefully out of the mold.
ANALYSIS

Pros Cons
Too much material left over, enough for a second pot. The pot didn't came out in one piece, glued the parts afterwards back together.


LEARNING LESSON
Maybe we should pull the pot out of the mold in the other direction, from the bottom.

TP3: the third knotpot result with glue adjustments

For this one we adjusted the amount of water. The reasoning to use more water was that the glue would spread more. The glue was too liquid and when under pressure, the glue came out of the mold. Therefore this experiment was absolutely a realization that the amount of glue was too high compared to the amount of fibers.

INGREDIENTS
40 g Japanese knotweed
110 ml water
55 g hide glue

SETTINGS
- ft
- minutes pressing time

STEPS
1° Heat the glue granules until it completely absorbs the water and has a sticky, homogeneous texture.
2° Measure the fibers and protein and add them to the hot glue.
3° Put it in the mold and press it like described in the setting.
4° After the pressing time, take the pot carefully out of the mold.

ANALYSIS

Pros Cons
The pot came out in one piece Not enough material
Too much glue


LEARNING LESSON
In this test we added too much glue compared to the amount of fibers.

Knotpot test with a different recipe

This cultivation pot is a new result of a different composed recipe. We added 1,7% water to the hide granules.

INGREDIENTS
40 g Japanese knotweed
36 ml water
22 g hide glue

SETTINGS
3,5 ft
30 minutes pressing time

STEPS
1° Heat the glue granules until it completely absorbs the water and has a sticky, homogeneous texture.
2° Measure the fibers and protein and add them to the hot glue.
3° Put it in the mold and press it like described in the setting.
4° After the pressing time, take the pot carefully out of the mold.

ANALYSIS

Pros Cons
This made us realize that maybe we don't need that much glue The mixture was too dry
The pot came out in one piece Not enough material
When dried, some parts crumbled more easily from the pot


LEARNING LESSON
The mixture felt dry and the result had not enough material to be full.

Smal glue adjustments

The test results of this recipe were pretty interesting. The mixture was more moist than the previous test that day, but it still felt dry. Because this sample came out nicely, we tried to make a couple samples with this recipe as a base.
INGREDIENTS
40 g Japanese knotweed
32 g hide glue
54 ml water added to the glue

SETTINGS
3 ft
40 minutes pressing time

STEPS
1° Heat the glue granules until it completely absorbs the water and has a sticky, homogeneous texture.
2° Measure the fibers and protein and add them to the hot glue.
3° Put it in the mold and press it like described in the setting.
4° After the pressing time, take the pot carefully out of the mold.
ANALYSIS

Pros Cons
The proportion material/glue is less than the previous test The pot is not filled up to the surface
It doesn't crumble like the previous test


LEARNING LESSON
The mixture felt still dry, but eventually the pot came out more in one piece. It feels like how dryer the mix, how better the material attaches to each other. In this test we think it has evrything to do with the glue composition.

Testing the same recipe as on 29/03/2022

This test has the same ingredients as the previous test just so we can evaluate the recipe. We wonder if this mixture is a good ratio or does it need some changes?

INGREDIENTS
40 g Japanese knotweed
34 g hide glue
57 ml water added to the glue

SETTINGS
1,5 ft
40 minutes pressing time

STEPS
1° Heat the glue granules until it completely absorbs the water and has a sticky, homogeneous texture.
2° Measure the fibers and protein and add them to the hot glue.
3° Put it in the mold and press it like described in the setting.
4° After the pressing time, take the pot carefully out of the mold.
ANALYSIS

Pros Cons
The pot is filled up to the surface The bottom is very thick, maybe to thick
When dried, it feels strong enough to carry a plant

TP4.2.3: the third outcome with the same recipe

This result also has the same ingredients as the test on 29/03. It's the third test so we can evaluate if this mixture works.

2° Measure the fibers and protein and add them to the hot glue.
3° Put it in the mold and press it like described in the setting.
4° After the pressing time, take the pot carefully out of the mold.
ANALYSIS

Pros Cons
The pot came out in one piece The bottom is thick, it doesn't have the same thickness as the surface
It was filled up to the surface
When dried this result feels strong as well
