The glass of a lens should be about the same Moh's hardness as quartz, 7, since it's predominately quartz. I have no idea about the hardness of coatings, but aren't they only a few molecules thick? Bill Pentax says its SMC coating is harder than glass. Very hard molecules... Andre

would expect even a vigorous cleaning with graphite would do nothing more than yield a very clean lens. Aric -Original Message- From: Bob Blakely [mailto:[EMAIL PROTECTED] Sent: Thursday, February 19, 2004 10:37 PM To: [EMAIL PROTECTED] Subject: Re: Lens Cleaning Problem - Volatile Liquids

It is much harder than talc. Think about it. From: "Rothman, Aric" <[EMAIL PROTECTED]> > Interestingly, carbon (graphite) is both the softest (tying with talc), and hardest (diamond) mineral, per Moh's > hardness scale. Depends on its molecular structure. > > I have no idea how the typical lens

This is absolutely not true concerning lamp or bone black. Carbon comes in many forms, polymorphs, e.g. crystalin as in diamond which is very hard indead, in sheet form as in graphite and only weakly bonded where it is very soft and will not wear bearings when used as a lubricant. Graphite hardness

I have no idea how the typical lens coating material compares in hardness, quantitatively speaking. We only know SMC is harder than the glass under it (dixit Pentax). Andre

The stuff is as soft as talc. No harm will come to your lenses or coatings from the lamp black. FYI, this is the substance preferred by photographers of yore. Be very careful not to spill it. If you do, and it's on the carpet, and you are married, you will probably soon be single. Regards, Bob...
