Quark (dairy product) manufactured by "Dairyland". Quark may also be available as "baking cheese", "pressed cottage cheese", or "fromage frais". In Australia, Ukrainian traditional quark is produced by Blue Bay Cheese in Mornington Peninsula. It is also sometimes available from supermarkets labelled as quark or quarg. In New Zealand, European traditional Kwark is produced by Karikaas in North Canterbury. It is available in 350g pots and available online and in speciality stores such as Moore Wilsons.

Quark that its transformations be allowed to vary with space and time – determines the properties of the strong interaction. In particular, it implies the existence of eight gluon types to act as its force carriers. Two terms are used in referring to a quark's mass: "current quark mass" refers to the mass of a quark by itself, while "constituent quark mass" refers to the current quark mass plus the mass of the gluon particle field surrounding the quark. These masses typically have very different values. Most of a hadron's mass comes from the gluons that bind the constituent quarks together,
