Il borace o tetraborato di sodio, anticamente noto col nome di tinkal o borace veneziano, è un importante composto del boro. Le forme più note sono il tetraborato di sodio anidro ed il tetraborato di sodio decaidrato (numero CAS:1303-96-4); trattasi quest'ultimo un cristallo morbido bianco, che si dissolve facilmente nell'acqua, e se lasciato esposto all'aria secca perde lentamente l'acqua di idratazione per diventare una sostanza gessosa bianca. Il borace venduto commercialmente è di solito completamente disidratato.
