A system for creating a rehydrated composition from a dehydrated precursor, where the precursor is in a reaction receptacle and is adapted to react chemically and/or physically with a heated liquid. The system includes a heated liquid delivery system which itself includes a liquid storage tank, a pump that is adapted to pump liquid from the storage tank, a process tubing system that is adapted to carry liquid downstream of the pump, an electrically-operated liquid heating element located downstream of the pump and that is adapted to heat liquid that is pumped through it by the pump, a liquid outlet through which heated liquid is delivered into the reaction receptacle, a controller that controls the pump and the heating element to establish at least one of the volume and temperature of the heated liquid delivered through the outlet and a user interface that is adapted to allow a user to establish control parameters of the controller, the control parameters comprising at least one of the volume and temperature of the heated liquid delivered through the outlet. The rehydrated composition is either a liquid that has a viscosity of at least 5 centipoise (cP), or a mixture that has a liquid component that has a viscosity of at least 5 cP.La présente invention concerne un système de création dune composition réhydratée à partir dun précurseur déshydraté, le précurseur étant placé dans un récipient de réaction et conçu pour réagir chimiquement et/ou physiquement avec un liquide chauffé. Le système comprend un système dadministration de liquide chauffé qui comprend lui-même un réservoir de stockage de liquide, une pompe qui est conçue pour pomper le liquide à partir du réservoir de stockage, un système de tubulure de procédé qui est conçu pour transporter le liquide en aval de la pompe, un élément de chauffage de liquide à actionnement électrique situé en aval de la pompe et qui est conçu pour chauffer le liquide pompé à travers celui-ci par la pompe, un orifice de sortie de
