MATERIAL DESCRIPTION

Salty Rice Clay made by equal- ratio mixing salt and Thai glutinous rice at room temperature.

The glutinous rice creates the super-strength mortar, this organic-inorganic compound was made possible by amylopectin, a type of polysaccharide, or complex carbohydrate. The amylopectin combines with the inorganic calcium carbonate from the lime to form a mortar that has more stable physical properties, greater mechanical strength. It has been found more stability by adding the salt (sodium chloride) with glutinous rice to creat a material with ductility, but also the ability to maintain a certain shape.

EXTRACTION PROCESS

1. Blend the rice and sea salt and filter it into a container as the rice clay.

2. Boil the rice with sea salt then stir until it become a paste.

3. Mix the salty rice clay with the rice paste.

4. Test the potential of the salty rice clay.
