Today we listened to the European Union’s research priorities and proposals from different countries. Germany and Sweden in particular highlight an important need for the future: lightweight materials. Light materials reduce energy consumption, for example in transportation. Sisusavi® can be used to make dishes so light that a gentle breeze will carry them along.

Greetings from Helsinki handicraft fair, where we presented Sisusavi® for the first time. Many interesting contacts were made there. The fair gave ideas into the development of Greenbutton’s products.

Sisus clay is suitable for small children, as it is easy to shape and does not harm if eaten. Depending on their age, the child can modify the colorless Sisusavi® and then dry it in room air. Dry parts can be glued together with Erikeeper and painted with watercolors or whatever colors small children use.

Indoor clay is suitable for adults and especially for those who know clay. At the fair, we heard how attached they were to clay. You can make a clay pot light when you mix paper in, and the paper burns off in the oven. You can also make the interior clay lighter, if you can leave air pockets inside the material.

A cup made of Sisusavi® does not break when dropped on the floor. However, we did not drop cups on the floor at the fair. We heard from somewhere in the distance that something had broken. The sound of the chips can be heard even further away, so breaking the glass cannot be done in secret.

A cup made of Sisusavi® either with a mold or a pottery wheel does not need an oven but dries at room temperature. If you build your work from several parts, the small pieces dry faster. Wood glue Erikeeper is very suitable for wet or dry gluing to Sisusavi®. We have tried coloring a dry object with watercolors, acrylic colors, liquid markers, oil colors and watercolor colors.

The object can be varnished with wood varnish and probably also with nail varnish, as one fair guest suggested.

One visitor to the fair thought that Sisusavi® does not have a completely flat surface. Yes, you can, as you can see in the pictures. The cellulose in the inner clay is a thousand or a hundred thousand times smaller than the millimeter-sized particles. In that respect, it is easy to believe that it will be even. 

When an adult does very precise work on Sisusavi®, it’s worth practicing and finding a new route to success. Sisusavi® is a completely new material and nobody knows much about it yet, what it can do.

At the fair many picked up the dishes and were amazed at their lightness. When the cups were in the hands of many people, we thought to wash them properly. So, we washed them with Fairy and rinsed well afterwards. We put the cups to dry in the dish drying cabinet.

The cups dried quickly, and we thought of drinking tea from them. It is good to drink hot tea from these cups because the material insulates heat transfer. The cup does not feel too hot in the hand.

The cups made of Sisusavi® are really light and sturdy. The cup can carry a large load. We compared Arabia’s Arctica coffee cup with one made from Sisusavi®, and the cup made from Sisusavi® was 72% lighter. Arctica weighed 113 grams and the cup made of Sisusavi® weighed 31 grams. Lightweight materials are the materials of the future.

The trend is towards light materials. Around the world, large sums of money are invested in the research of lightweight materials.

Sisusavi® already exists, although lightness is only now being announced more.
