GELATIN

BIO FOAM

How To:

1. Warm up the water in a pot on your stove.

2. Add your plasticiser, the glycerine will bond with the gelatin.

3. Add the gelatin.

4. Mix gently the ingredients until they form a smooth mix. Agar can take longer to fully dissolve, if the mix is not smooth, add a gentle heat at 60C to make sure the ingredients mix.

5. Add a table spoon of dishwashing soap to the mixture.

6. Simmer for 10-15 minutes (80C max) Whisking constantly.

7. Prepare the surface and molds.

8. For colouring, prepare your colours in a jar or a small container, to which you will add the mixture once it's ready for casting.

9. Once your mixture has thickened, almost like a syrup, pour on your chosen surface. Once start pouring, try to cast slowly, without inglobating air, and by carefully pouring on the liquid itself.

10. Let the mould dry in a ventilated and dry room, turninng your piece until its dry will help you preventing mould formation, but might affect deformaton due to water loss.

BIO RESIN

How To:

1. Warm up the water in a pot on your stove.

2. Add your plasticiser, the glycerine will bond with the gelatin.

3. Add the gelatin.

AGAR

AGAR FOIL

How To:

1. Warm up the water in a pot on your stove.

2. Add your plasticiser, the glycerine will bond with the Agar.

3. Add the Agar.

4. Mix gently the ingredients until they form a smooth mix. Agar can take longer to fully dissolve, if the mix is not smooth, add a gentle heat at 60C to make sure the ingredients mix.

5. Simmer for 20 minutes (80C max)

6. Prepare the surface and molds. Due to the large amount of water needed for dissolving agar, the casted plastic will shrink both in thickness and width.

7. For colouring, prepare your colours in a jar or a small container, to which you will add the mixture once it's ready for casting.

8. Once your mixture has thickened, almost like a syrup, pour on your chosen surface. Once start pouring, try to cast slowly, without inglobating air, and by carefully pouring on the liquid itself.

9. Let the mould dry in a ventilated and dry room,with agar it is necessary to keep the piece in the mould for a smooth effect.

AGAR AND GELATIN FOIL

1. Warm up the water in a pot on your stove.

2. Add your plasticiser, the glycerine will bond with the Agar and Gelatin

3. Add the Agar and Gelatin.

4. Mix gently the ingredients until they form a smooth mix. Agar can take longer to fully dissolve, if the mix is not smooth, add a gentle heat at 60C to make sure the ingredients mix.

5. Simmer for 20 minutes (80C max)

OBSERVATION

• Agar shrinks more than Gelatin.
• Agar is opaque and gelatin is transparent.
• Wool helped with keeping the original shape of the agar foil solution.

ALGINATE

	Alginate 60gr	Glycerine 100ml	1lt	Sunflower Oil 50g	Opaque

Curing Solution

Calcium Chloride	1 0g	Water	100ml

ALGINATE YARN

How To:

1. Add the destilated water in the measuring cup, alginate powder, glycerol and blend them with blender.

2. Leave the mixure overnight so there isn't any bubbles.

3. Extrude the mixure in a bowl of curing solution with a syringe.

4. Wrap the alginate yarn around a cylinder.

5. Leave to dry.

ALGINATE BIOPLASTICS

How To:

1. Add the destilated water in the measuring cup, alginate powder, glycerol and blend them with blender.

2. Leave the mixure overnight so there isn't any bubbles.

3. Pour the alginate mixture onto the fabric. Spray more calcium chloride on the alginate.

4. Leave to dry.

WATER SOLUBILITY

Alginate bioplastic fully dissolves in cold water after 1 hour. But Cecillia pointed out that it is mostly because the alginate bioplastic wasn't completely dry yet. It should be waterproof. So my experiment will continue!

FISH LEATHER

We got some salmon skin and eel skin from the local fish shop.

For Preparation:

1. Remove flesh and fibers on the fish skin.

2. Remove the scales.

3. Clean it with a bit of ethanol.

LOTTA RAHME on FISH LEATHER TANNING

Lotta's masterclass tells you everything about tanning fish leather with egg yoke and oil :)

Don't forget to massage your fish once in a while!

After tanning, the fish skin is hard and dry, wash it with water and a bit of soap until it's soft. Give it a massage around a cylinder and leave it to dry again.
