Sisusavi® is an eco-friendly modeling material that makes it easy to create people, cups, and all kinds of other objects. It is also suitable for making vintage-style items. One of its unique features is that finished objects can be recycled into new creations again and again, as the material can be returned to its original state. Sisusavi is safe to use and is made from compostable, renewable materials.
Sisusavi does not create a mess, and no protective clothing is required when working with it. It can be thrown on a pottery wheel just like traditional clay. The material is gluten-free and made entirely from renewable resources. It is ideal for producing lightweight objects. Sisusavi air-dries into a durable finish, and once dry it can be sanded, carved, decorated, and painted. The material can also be colored throughout by thoroughly mixing pigment into the mass before shaping.
Sisusavi is ready to use straight out of the package, but it should be stored in an airtight container. If it becomes too dry, it can easily be restored by adding a small amount of water.
The material dries slowly at room temperature. If faster drying is needed, finished objects can be placed in a conventional oven at a moderate temperature or dried using other suitable methods. A microwave oven can also be used, but only with great care.
I wanted to investigate the air-drying modeling materials currently available on the market. I purchased eight different products, some intended for professional use. Using each material, I made a mold of a human face and also formed a ball to compare their properties.
Some materials had strong odors, while many were hard and slippery to work with. Others stuck so firmly to my hands that removing them was difficult. Several products carried so many safety warnings that I decided to wear protective gloves and a face mask while handling them. I was also surprised that I could not even make a simple ball with every material. Sisusavi®, however, made this easy.
I weighed both the balls and the molded faces. I was surprised that even objects made from paper-based modeling compounds were relatively heavy. This is often because such materials contain mineral fillers or stone-like additives in addition to paper fibers. The objects made from Sisusavi® were the lightest of all.
Many modeling compounds contain polymers, synthetic adhesives, or other plastic-based ingredients, which means they must generally be disposed of as mixed waste. 
I then immersed the balls in water. To my surprise, every material except Sisusavi® gradually began to dissolve. 
The balls made from Sisusavi® remained intact for several days without breaking down at all. 
When you want to recycle a Sisusavi object, the process is carried out in water. As little water as possible should be used so that the reclaimed material does not become too wet. Sisusavi does not dissolve on its own in water, but it can be broken down mechanically by kneading or crushing it. 
The particles should be made as small as possible. If excess water separates from the material, it should be removed. Once the consistency is suitable, the reclaimed Sisusavi can be used to create entirely new objects. 
Soft Sisusavi is an ideal material for art, leisure activities, and hobbies, as well as for educational use in schools, daycare centers, and other learning environments.
