Step one

1. Wash the mussel shells and remove remaining waste.

2. Cook the shells for 15 minutes.

3. Heat the shells for 1 hour on 200 degrees in the oven. This will make the shells more brittle .

4. Grind the shells into a powder.

5. Sieve the grinded shells to obtain a powder with particle size of 40 micron.

Step two

1. Measure the desired amount of NEO-Alginate (2% of total weight).

2. Measure the desired amount of water (98% of total weight).

3. Add alginate to the water and stir until a gel has formed.

Step three

1. Measure the desired amount of mussel shell powder

2. Add binder to the powder until the right ratio is met. The powder:binder ratio is 1:0,4

3. Stir until the ingredients are well mixed into a smooth paste
