====How to produce the material ?==== | ====How to produce the material ?==== | ||
+ | |||
+ | ===Step 1 - Eggshells=== | ||
+ | |||
+ | * Get some eggshells. | ||
+ | * Rince them so that they are clean. | ||
+ | * Carefully remove the inner skin/ | ||
+ | * Crush them in bits as tiny as possible. | ||
+ | |||
+ | ===Step 2 - Flour=== | ||
+ | |||
+ | * Mix flour in excess of water. | ||
+ | * Let it sit for a while. | ||
+ | * Once you can see two fractions, a solid one sitting at the bottom of the flask, and some white water on the top, discard the water fraction and keep the solid fraction. | ||
+ | |||
+ | This step aims at dissolving the starch contained in the flour, and keep only the glutinous fraction of the flour. | ||
+ | |||
+ | ===Step 3 - Mixing=== | ||
+ | |||
+ | Mix the glutinous fraction of flour with crushed eggshells. | ||
+ | |||
+ | The proportion changes the nature of the material. Chloé goes for 2/3 wet flour for 1/3 crushed eggshells, but she says that half-half is also fine. | ||
+ | |||
+ | ===Step 4 - Forming=== | ||
+ | |||
+ | You can either mold it, or use a syringe as an extruder. | ||
+ | |||
+ | ===Step 5 - Drying=== | ||
+ | |||
+ | Then, just let it dry overnight. | ||
+ | |||
+ | You can accelerate drying by using a microwave. One minute at 1000 W is too much, but five minutes on the grill position were fine. | ||
+ | |||
+ | ===Final Result=== | ||
+ | |||
+ | We ended up with slightly plastic objects of diverse shapes. They do not hold water very well and start to disagregate if they contain/are dipped in a liquid. This material is therefore more for decorative purposes, as a coating on vases, for instance. | ||

- | ====Conclusion==== | + | We tried to replace crushed eggshells by some mineral powder with found in a jar here at FoAM. However, it did not work out well, as many cracks appeared when drying. |
