This serie of engobes has been specially elaborated for the development of the techniques of:“Iberian Decoration” and “ Socarrat”. Both of them have in commune the use of two colours: Red and Black, that originally consisted in: Natural Red Iron Oxide and Natural Manganese Dioxide, respectively. Because of this and in order to make the application easy, we have created the engobes DI Red and DI Black. That due to their characteristics of formulation they permit us to reproduce these techniques.
