Cake or syringe using a coupler. The bag or syringe is partially filled with icing which is sometimes colored. Using different piping tips and various techniques, a cake decorator can make many different designs. Basic decorating tips include open star, closed star, basketweave, round, drop flower, leaf, multi, petal, and specialty tips. An embossing mat is used to create embossed effects. A cake turntable that cakes are spun upon may be used in cake decoration. Royal icing, marzipan (or a less sweet version, known as almond paste), fondant icing (also known as sugarpaste), and buttercream are used as covering icings and
Foam not have interconnected pores. The closed-cell foams normally have higher compressive strength due to their structures. However, closed-cell foams are also, in general, a more dense foam, require more material, and as a consequence are more expensive to produce. The closed cells can be filled with a specialized gas to provide improved insulation. The closed-cell structure foams have higher dimensional stability, low moisture absorption coefficients, and higher strength compared to open-cell-structured foams. All types of foam are widely used as core material in sandwich-structured composite materials. The earliest known engineering use of cellular solids is with wood, which in its
