Fabriqué este pomo para ponerlo en el Ático para Manuela. Son unas rocas que recogí de una mina de hierro abandonada en Soria, con varilla roscada y tuercas. Tratadas con tapaporos, endurecedor y barniz para no teñir sin querer las manos de quien los utilice. Abren y cierran un baño escondido entre armarios. Es una pista y un guiño al interior, “visitando al Sr. Roca”. El color también acompaña. 

I made this door knob to put in Manuela's Penthouse. They are rocks that I collected from an abandoned iron mine in Soria, with threaded rods and nuts. They have been treated with a filler, hardener, and varnish so as not to unintentionally stain the hands of those who use them. They open and close a bathroom hidden between cabinets. It is a clue and a wink to the interior, "visiting Mr. Roca" *. The color also helps.  
*Roca means rock and it is also an important brand of sanitary material in Spain.
