Consistent with four time Olympic medalist summer time Sanders, specially because the photographers steadily ask them to until they do it, normally on the quit of the podium image shoot classes.  The culture probable stems from the age antique practice of trying out whether some thing turned into actually stable gold or no longer by means of biting it.  Gold is a totally smooth metallic, at the least softer than enamel enamel, and if it’s fairly natural, you need to be able to depart some enamel marks in it by means of biting it.  The exercise of biting valuable metals also allowed human beings to see if perhaps the gold item was without a doubt simply gold plated, with some thing like lead at the middle.  in that case, the gold plating could be scraped off with your tooth and, given the regularly bitten gold coins weren’t that thick, the plating tended to be fairly skinny, so that you didn’t must chunk too hard to discover whether it changed into surprisingly 24-karat gold or now not.

Manifestly Olympic gold medals nowadays aren't made from strong gold (now not in view that 1912, though they do have 24k gold plating).  alternatively, the gold medals are made usually of sterling silver.  however have been you to honestly chunk down on the gold plated silver Olympic medal, you must be capable of make a dent as silver is likewise softer than enamel teeth, but tougher than gold.

The usage of Mohs mineral hardness scale, we see that enamel teeth is rated at a 5, whilst gold is rated at round 2.5 and silver at a 2.7-ish.  enamel teeth is also higher on the dimensions than copper, which the “bronze” Olympic medals are more often than not made from, so it’s feasible to make tooth marks on the ones too.

Mohs hardness scale is a relative hardness scale created through German geologist Friedrich Mohs in 1812, rating things based on scratching one cloth in opposition to any other, the one that makes a mark on the alternative is rated as  tougher.  If each scratch each different, they may be taken into consideration to be the equal hardness.

For reference, glass is rated at 5.five and teeth enamel is sincerely barely higher than metal or platinum (at four-four.5).  (be aware: just because something is simplest barely better in this in particular scale than some thing else doesn’t always imply it’s only slightly harder.  as an example, diamonds are rated at a 10, at the same time as corundum is rated at 9, however diamonds are four instances as tough as corundum.  further, corundum is twice as tough as topaz, that's rated at an eight.)

Despite the fact that not one of the athletes are certainly looking to make marks on their medals or checking for authenticity, the subculture with Olympians has continued and photographers actually gained’t permit it die because it makes a extra thrilling, “playful” shot over an Olympic medalist really keeping their medal up next to their faces or the like.
