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
Sea foam include petroleum compounds, pesticides, and herbicides. Structurally, sea foam is thermodynamically unstable, though some sea foam can persist in the environment for several days at most. There are two types of sea foam categorized based on their stability: 1) Unstable or transient foams have very short lifetimes of only seconds. The bubbles formed in sea foam may burst releasing aerosols into the air, contributing to sea spray. 2) Metastable foams can have a lifetime of several hours to several days; their duration is sometimes attributed to small particles of silica, calcium, or iron which contribute to foam stability and longevity.
