The vaqueta ball (Valencian: pilota de vaqueta, IPA: [piˈlɔta ðe vaˈketa]; vaqueta meaning "little cow") is the kind of ball used to play some Valencian pilota variants: Escala i corda, Galotxa and Raspall. Its name derives from the fact that it is made of bull's skin, hence its black colour (that tends to become brown as it is used), this way the ball contrasts with the white colour of the trinquets' walls.
The vaqueta ball has a diameter of 44 mm, its circumference is 138 mm, and its weight is around 42 and 48 gr, depending on the variant (in Escala i corda lighter balls are preferred, while in Raspall heavier balls are used).
The actual weight of the balls is the end of a process, that is, historical pilotaris such as Quart in the 1930s played with balls around 28 and 33 g. The lighter the ball the slower it goes and the less it flies (its direction). This change of weight has been favoured by "rest" players, who tend to be stronger and have to send the ball longer, but it is an extra handicap for "mitger" and "punter" players, who have to stop the ball or strike it in the middle of its trajectory and while it is still carrying a lot of force.
During the matches, and before beginning every "quinze", the team who stands at the "dau" is allowed to change one of the six disposable balls (each team previously chose three of them). This way, if playing again a double team, a trio would choose a new ball, which are fast and with a long bounce, so that the opposing two players are forced to move constantly. Otherwise, the attacking team tends to choose heavier balls, since they exhaust more when defensing.
The making of a vaqueta ball is a piece of Arts and crafts. The "piloters" are mainly leather workers such as Emili López (Alberic), Enric Álvarez (Carcaixent), Miquel Baixauli (Catarroja), Joan Montañés (Llíria), Josep Bernet (Massalfassar), and Miquel Pedrosa (La Vall d'Uixó), or retired players as el Rovellet (València).
