A molten wax applicator for use in building up wax patterns and forms, particularly in dental applications. A hollow, heated stock provides a reservoir for holding molten wax. A nozzle having a wax-dispensing tip connects to the stock. A conduit through the nozzle interconnects the reservoir with the dispensing tip. A valve raceway intercepts the conduit. A valve incorporating resilient, polymeric conduit-sealing elements works in the raceway. A valve actuator with associated lock is connected to the valve for shifting it between open and closed positions permitting, in the open position, controlled dropwise or continuous flow of molten wax to the work.
