high coefficient of friction with glass

[steve30]

Hello,
Which materials have a high coefficient of friction with glass ?
The material wil be used to design a spherical support (4 mm) for a flat glass surface (point contact)
Thanks

suggest a material that does not introduce surface flaws or cracks when contact is made. ever think about rubber or latex material?

then again, weight of glass and number of supports will need to be determined.

good luck.

Rubber.

Typically, the softer the compound the higher the friction.
