Icing (food) desired colour. Sprinkles, colouring mist, edible ink designs, or other decorations are often used on top of icing. The simplest icing is a glacé icing, containing powdered sugar and water. This can be flavoured and coloured as desired, for example, by using lemon juice in place of the water. More complicated icings can be made by beating fat into powdered sugar (as in buttercream), by melting fat and sugar together, by using egg whites (as in royal icing), and by adding other ingredients such as glycerin (as in fondant). Some icings can be made from combinations of sugar and cream
Reticulated foam evaporate the water then fuse the ceramic particles and finally to burn off the organic polymer. Reticulated metal foam can also be made using polyurethane foam as a template similar to its use in ceramic foams. Metals can be vapor deposited onto the polyurethane foam and then the organic polymer burned off. Reticulated foams are used where porosity, surface area, low density are important. Reticulated foam Reticulated foam is a very porous, low density solid foam. 'Reticulated' means like a net. Reticulated foams are extremely open foams i.e. there are few, if any, intact bubbles or cell windows. In contrast,
