Question: What type of mixture is Vaseline?

Context paragraphs:
Bafat: Bafat (or Baffat) is a type of masala, a mixture of spices.  It is commonly made with a mixture of dried and ground chilli peppers, coriander seeds, cumin seeds, mustard seeds, black peppercorn, turmeric, cinnamon and cloves.  Baffat is commonly used in Mangalorean cuisine and, due to the Portuguese influence in the area, is a combination of Indian and Portuguese flavors.  Bafat is regarded as a pork seasoning , but is also used to season other meats, and sometimes vegetables.

Kiyoshikōjin Seichō-ji: Kiyoshikōjin Seichō-ji (清荒神清澄寺 ) is a Shingon Buddhist temple in Takarazuka, Hyōgo, Japan.  It is one of the typical type of mixture of Shintoism and Buddhism temples in Japan, and temple's name has two Chinese letters of two religions in Japan together, 'Jin'(神) of Shintoism and 'Ji'(寺) of Buddhism.  This type of mixture of two religions, called 'Shinbutsu shugo'(神仏習合) was very common among Japanese temples or shrines until the Edo period, but the two religions were formally and forcedly separated by Meiji Government in the last half of the 19th century.  In this sense, this temple is a good example that still preserves Japanese religious traditions before modernization.

Grease (lubricant): Grease is a semisolid lubricant.  Grease generally consists of a soap emulsified with mineral or vegetable oil.  The characteristic feature of greases is that they possess a high initial viscosity, which upon the application of shear, drops to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil used in the grease.  This change in viscosity is called shear thinning.  Grease is sometimes used to describe lubricating materials that are simply soft solids or high viscosity liquids, but these materials do not exhibit the shear-thinning properties characteristic of the classical grease.  For example, petroleum jellies such as Vaseline are not generally classified as greases.

Ledeburite: In iron and steel metallurgy, ledeburite is a mixture of 4.3% carbon in iron and is a eutectic mixture of austenite and cementite.  Ledeburite is not a type of steel as the carbon level is too high although it may occur as a separate constituent in some high carbon steels.  It is mostly found with cementite or pearlite in a range of cast irons.

Bekhterev's mixture: Bekhterev’s Mixture (Russian: Микстура Бехтерева , MixturaBechtereva) is a medicine with a sedative effect, affecting the central nervous system.  The mixture was proposed by famous Russian neurologist Vladimir Bekhterev and subsequently named after him.  One of the oldest and most popular medicines of its type, it is used to treat light forms of heart failure, panic disorder, and dystonia.  The medicine is known to be well tolerated, with no contra-indications, except bromine sensitivity (may cause rashes).

Flash-gas (petroleum): In oil and gas production, flash-gas is a spontaneous vapor that is produced from the heating or depressurization of the extracted oil mixture during different phases of production.  Flashing, or flash evaporation, is the term that describes this process of volatile components suddenly vaporizing from their liquid state.  This often happens during the transportation of petroleum products through pipelines and into vessels, such as when the stream from a common separation unit flows into an on-site atmospheric storage tank.  Vessels that are used to intentionally “flash” a mixture of gas and saturated liquids are aptly named "flash drums."  A type of vapor-liquid separator.  A venting apparatus is used in these vessels to prevent damage due to increasing pressure, extreme cases of this are referred to as boiling liquid expanding vapor explosion (BLEVE).

Gas chromatography: Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition.  Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture (the relative amounts of such components can also be determined).  In some situations, GC may help in identifying a compound.  In preparative chromatography, GC can be used to prepare pure compounds from a mixture.

Petroleum jelly: Petroleum jelly, petrolatum, white petrolatum, soft paraffin/paraffin wax or multi-hydrocarbon, CAS number 8009-03-8, is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25), originally promoted as a topical ointment for its healing properties.

Ratafia: Ratafia is a term used for two types of sweet alcoholic beverage, either a fortified wine or a fruit-based beverage.  The latter type is a liqueur or cordial flavoured with lemon peel, herbs in various amounts (nutmeg, cinnamon, clove, mint, rosemary, anise, etc.) typically combined with sugar.  It may also be prepared with peach or cherry kernels, bitter almonds, or other fruits, as many different varieties are made.  The same name is given to a flavouring essence resembling bitter almonds, and also to a light biscuit.  The former type is a type of "mistelle", a mixture of marc brandy and the unfermented juice of the grape, and it is the type of Ratafia produced in France.

Pulse detonation engine: A pulse detonation engine (PDE) is a type of propulsion system that uses detonation waves to combust the fuel and oxidizer mixture.  The engine is pulsed because the mixture must be renewed in the combustion chamber between each detonation wave and the next.  Theoretically, a PDE can operate from subsonic up to a hypersonic flight speed of roughly Mach 5.  An ideal PDE design can have a thermodynamic efficiency higher than other designs like turbojets and turbofans because a detonation wave rapidly compresses the mixture and adds heat at constant volume.  Consequently, moving parts like compressor spools are not necessarily required in the engine, which could significantly reduce overall weight and cost.  PDEs have been considered for propulsion since 1940.  Key issues for further development include fast and efficient mixing of the fuel and oxidizer, the prevention of autoignition, and integration with an inlet and nozzle.
