Melange is a freeware application which was designed to let you calculate the prices of mixtures (recipes) from two tables: one describing the compositions of mixtures and one table containing the prices of components. The application is completely SQL-driven (SQLite3).
Melange (french for mixture) is meant for businesses that have to manage dozens of recipes containing ingredients which costs may vary considerably depending on oil-prices or season. This holds especially true in situations where ingredients or components are present in more than one mixture in varying amounts. Thus, this program is a valuable tool to see how fluctuating prices of starting materials propagate in products derived from them.
Businesses include cosmetics, industrial emulsions, paints, detergents, food stuffs, waxes, oils, etc. An up-to-date price-list of products (without production, packaging and labelling costs) is of utmost importance.
