tools. cooker/stove/hotplate, teaspoon, measuring cup, cooking pot, scale, thermometer, stirring spoon, flat surface
process. cast, cooked, air dried
composition. 4gr agar agar, 2.5 ml glycerol, 420 ml water
Instructions.
Step one
Mix all of the ingredients together in a pot in the amounts above, and stir until agar and glycerol dissolve in the water.
Step two
Put the pot on the stove and heat the mixture to 95o C or to just below boiling. Keep stirring the whole time. When it reaches 95o (or begins to froth), remove from the heat. Keep stirring and skim off any of the froth from the top with a spoon. Any froth left on the surface will cause air bubbles in your plastic sheet.
Step three
Pour liquid onto a flat surface or mold. A silicon sheet works well with a frame (you can cut this from scrap wood), or alternatively, lay a silicon sheet on a baking tray with edges. Let dry for 1-2 days, depending on temperature and humidity levels.

tools. cooker/stove/hotplate, teaspoon, measuring cup, cooking pot, scale, thermometer, stirring spoon, flat surface
process. cast, cooked, air dried
composition. 1.6 gr agar agar, 2.7 ml glycerol, 40 ml water
Instructions.
Step one
Mix all of the ingredients together in a pot in the amounts above, and stir until agar and glycerol dissolve in the water. Then heat the mixture to boiling point, and simmer for 15 - 20min, stirring constantly.
Step two
Scoop out excess froth with a spoon, and make sure there are no clumps. Carefully pour the mixture onto a surface of acrylic or plastic with a frame.
Step three
After 4-5 hours lift and let it dry hanging. How long it takes will depend on the temperature and humidity in the room, and it may take several days (depending on your formulation). You won’t be able to remove the plastic from the drying sheet easily until it is completely dry, so be patient! If your first batch turns out too sticky or slimy, you can try it again with slightly less plasticiser.

city. Lisbon
tools. scale, grinder, sieve machine, stirring spoon, containers, 40 micron sieve
process. 3D printed, ground, mixed, air dried
composition. 29.4% water, 0.6% alginate, 70% mussel shells
Instructions.
Step one - powder
-
Wash the mussel shells and remove remaining waste.
-
Cook the shells for 15 minutes.
-
Heat the shells for 1 hour on 200 degrees in the oven. This will make the shells more brittle .
-
Grind the shells into a powder.
-
Sieve the grinded shells to obtain a powder with particle size of 40 micron.
Step two - binding
-
Measure the desired amount of NEO-Alginate (2% of total weight).
-
Measure the desired amount of water (98% of total weight).
-
Add alginate to the water and stir until a gel has formed.
Step three - paste prep
-
Measure the desired amount of mussel shell powder
-
Add binder to the powder until the right ratio is met. The powder:binder ratio is 1:0,4
-
Stir until the ingredients are well mixed into a smooth paste
