Have you
ever rubbed paraffin, better, under some pressure, whether between
fingers or between links? It is not slippery.

Have you never walked on a freshly waxed floor? Have you never waxed wooden drawers? The phenomenon you are describing is viscosity.


First what do you mean by waxed floor? Coated with paraffin wax?
Coated with a mixture of paraffin wax and mineral oil? A commercial liquid wax? What is in it?

Paste floor wax -- the old-fashioned kind. What's in it? Wax and solvents usually.


A wood or linoleum floor coated with a film of paraffin wax is not slippery.

Sure it is.


You cannot talk about a `freshly waxed floor' without specifying the entire situation.

Simple old floor wax, that's all. It is used to shine, but more importantly to protect the surface from wear and scuffs. It forms a durable film.


Surfers, at the time I saw them, coated the tops of their boards with paraffin wax to give them traction for the soles of their feet.

Wax sticks well to plastic, and because it's hydrophobic will displace the water film between the board and skin. Sticky wax is still sticky under water. Rub a candle under water.


An unfinished wood surface is porous. Steel is not.

So what? Wax sticks to both surfaces.

A wooden drawers and runners is a low pressure situation. A bicycle chain is extremely high pressure. The paraffin wax quickly migrates away from the mating surface, never to return.

Wax has high film strength, that's what makes it prevent floor scuffs.

" Solid and dry film lubricants vary widely in terms of chemical composition. Some products contain boron nitride (BN) or “white graphite”, a chemically inert compound that provides high thermal conductivity and low thermal expansion. Hexagonal or flake graphite, molybdenum, and metal sulphide are solid lubricants that maintain a low coefficient of friction up to 400° C (752° F) and are available in powder, sprayable coating, and solid machinable forms. Products that are based on halogenated hydrocarbons include chlorofluorcarbon (CFC), halogenated fluorocarbon (HFC), halogenated chlorofluorocarbon (HCFC), and perfluorocarbon (PFC). **Wax, paraffin and stearate compounds are suitable for some lubrication, anti-corrosive and anti-static applications**. Fluoropolymer-based compounds include polytetrafluoroethylene (PTFE)."

You never used waxed dental floss?
