Fondant icing a supersaturated solution until nucleation occurs. While the solution is supersaturated, if a cook puts a seed crystal (undissolved sucrose) into the mix, or agitates the solution, the dissolved sucrose crystallizes to form large, crunchy crystals (which is how rock candy is made). However, if the cook lets the solution cool undisturbed and then stirs it vigorously, it forms many tiny crystals, resulting in a smooth-textured fondant. Fondant icing Fondant icing, also commonly referred to simply as fondant (, ), is an icing used to decorate or sculpt cakes and pastries. It is made from sugar, water, gelatin, butter, and
Acoustic foam used to improve the acoustics of the room, which thereby reduces noise in the room. Acoustic foam typically deals more with the mid and high frequencies. To deal with lower frequencies, much thicker pieces of acoustic foam are needed; large pieces of acoustic foam are often placed in the corners of a room and are called acoustic foam corner bass traps. Acoustic foam Acoustic foam is an open celled foam used for acoustic treatment. It attenuates airborne sound waves by increasing air resistance, thus reducing the amplitude of the waves. Acoustic foam can be attached to walls, ceilings, doors, and
