### substance | liquid | ethanol:

Acute ethanol
* induces endothelial dependent carotid artery constriction.
* inhibits muscarinic hippocampal neurons.

Brazilian ethanol
* is produced from sugar cane and noted for high carbon sequestration.
+ Gasoline, Usage and pricing, Brazil: Fuel :: Hydrocarbons
  * Brazil has the largest national fuel ethanol industry. Brazilian ethanol is produced from sugar cane and noted for high carbon sequestration.

Flammable liquid
* Most flammable liquids are lighter than water
  - vaporize readily leading to high concentrations in air
* Some flammable liquids are hazardous wastes.
* Store all flammable liquids away from equipment and appliances.
* are the main hazard most commonly found in the laboratory
  - most common accelerants
* present a fire hazard at or below room temperature.

Hot liquid
* are less dense and therefore more buoyant than cold liquids
  - the leading cause of nonfatal burns
* burn just like fire.
* can badly burn an infant
  - cause life-threatening burn injuries
* cause many scalding accidents.
* has characteristic odour.
* have larger volumes than cold liquids.

### substance | liquid:

Ink
* Most ink carries pigment.
* Most ink contains little solid matter
  - has color
  - inks are water soluble and can easily be washed off before it completely dries
* Some ink absorbs light.
* Some ink contains dioxide
  - titanium dioxide
  - inks are pigmented, some are water based.
  * ' liquid that is used to write, draw, print, or make marks. Ink is used in pens, in some computer printers, and in printing presses. In some countries, people write by using ink and brushes. People usually write or print using black ink, but ink can be any color
* also affects the flatness of DVDs more than CDs
  - contain damaging acid
* are a variable in process printing
  - of different types and colors, of course
* are the most light-stable in the lithographic industry
  - same pigments as in oil paints, but in a paste-like medium instead of linseed oil
  - water soluble inks
* can be more intense than pencil or chalk, etc
  - shine or shimmer, or lie flat and still
  - skin over- trap solvent in the ink, causing odor, picking on subsequent rollers
  - sometimes 'bleed' through
* contain acids that can eat into a photograph.
* cures at low integral light
  - fast and little odor remains after cure
* dating The dating of inks is done in three primary forms.
* dry immediately and remain water-fast.
* drying takes place mainly by absorption, with a limited amount of oxidisation.
* fixed to a physical surface is the basic condition or form of print.
* flows evenly and smoothly on all materials, for a dense opacity.
* frequently get their color from the metals or hazardous pigments they contain.
* is delivered to cells and transferred to material
  - easier to read than pencil
  - faded in places, especially at the edges
  - hard to get off of cords, since it tends to soak into the plastic on the cord
* is made by using oil to hold pigments and other compounds together
  - to show up under a a black ultraviolet light
  - on raised surface of a matrix
  - transferred from a plate to the printed surface by direct contact
  - to color the body and is applied in two or more coats
* meets requirements.
* pigmented liquid.
* runs, leaches, and fades over time and is hard to erase and correct.
* seem to be less tolerant of heat variation than toners.
* simply reflect incident light.
* stiffen up when too cold and age-up when too hot.
* used on packaging are environmentally safe and contain no heavy metals or solvents.
+ Marker: Art :: Writing tools
  * A 'marker' is a writing device that allows a person to draw, write, or scribble. Ink comes out of the tip of the marker and onto the writing surface, commonly a piece of paper. Markers generally come in a variety of different colors.
