Foam For Material Activists by Laura Velgersdijk

HOW TO MAKE HONEYFOAM INSPIRATION The honeyfoam recipe is based on Margaret Dunne’s gelatin foam recipe from her Bioplastic Cook Book. Her recipe is made from 60g glycerin, 60ml water, 45ml gelatin and 6ml soap. The different qualities of this recipe and the honeyfoam is the thickness and strength of the material. The gelatin foam is a lot less strong and thick than the honeyfoam. This makes it tear easier when sharp objects are pressed against it, but it can also tear easily when pressing on it too hard. The material bounces back a lot more when pressed on it and the surface has a lot of air holes from bubbles.

There is also one different tool used in the hoenyfoam recipe. I noticed when i first started to make foam recipes that the bottom half of the foam will often be solid while the top half is foam. The foam is too heavy and presses the lower half together making all the air disappear, which makes it a solid form. To prevent this I tried to speed up the cooling proces by storing the freshly casted foam in the freezer. This way the foam has no time to press the air out of the bottom half because it’s already become hard.
