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. In the United Kingdom, fat-free quark is produced by several independent manufacturers based throughout the country. All the big four supermarkets in the UK sell their own
Quark star temperatures and/or pressures. This suggests that the only stable quark stars will be neutron stars with a quark matter core, while quark stars consisting entirely of ordinary quark matter will be highly unstable and dissolve spontaneously. It has been shown that the high Fermi energy making ordinary quark matter unstable at low temperatures and pressures can be lowered substantially by the transformation of a sufficient number of u and d quarks into strange quarks, as strange quarks are, relatively speaking, a very heavy type of quark particle. This kind of quark matter is known specifically as strange quark matter and
