The evolution of Carbon 60

The Carbon 60 molecule was first theorized in 1970 by Buckminster fuller. Buckminster Fuller was a renowned architect, theorist, and philosopher. His work in the architectural field was highly influential in changing the way people approached architecture and geometry. Though he may not have discovered the molecule himself, he played a crucial role in helping others to understand the concept of this intriguing molecule.

In the early part of the 1980s, a group of men lead by David Walton and Harry Kroto, began to use a new technique of using lasers and electrical arcs to vaporize Carbon and other elements. Their goal in this was to study different forms of Carbon.

Using a similar technique, Harry Kroto and Richard Smalley, and Robert Curl, discovered the C60 molecule by arcing two carbon rods in a helium gas environment. This technique also produced C70 and other allotropes of Carbon.

The team figured out that dissolving the mass of different allotropes of Carbon in toluene would separate the C60 out of the soot. The Carbon 60 saturated in the toluene was dried to remove most of the toluene solvent. After many tests (including the most definitive test the TOF-MALDI Mass spec), the team found that they did have Carbon 60. The team named the molecule after Buckminster Fuller, calling it the: Buckminsterfullerene, Fullerene, or Buckyball.

For this incredible discovery, Harry Kroto, Robert Curl, and Richard Smalley were awarded the Nobel Prize in Chemistry in 1996

Many years later, researchers began to discover the antioxidant properties of C60. Many companies began to sell Carbon 60 as a nutritional supplement due to its ability to neutralize free radicals.

In 2012, Bob Greska, a forty-year aerospace carbon materials engineer, discovered an improved process to produce impurity-free Carbon 60 molecules making them the only safe for biological use Carbon 60 molecules. Mr. Greska’s exclusive process now produces the only food-grade Carbon 60 in the world, His nano size, spherical, non-crystalline Carbon 60 molecules.

Greska’s solvent-free process produces a smaller form of Carbon 60 due to the fact that his Carbon 60 molecules are not bound by solvents.

Bob Greska revolutionized the C60 market by bringing the only Non-Solvent Extracted, Food-Grade Carbon 60 to the market.

    I am curious as to how much solvent is left after 12 hrs or so of vacuum heating? How do they get away with claiming their products are solvent free?

      Hi Josh Dove! There is about 20% by weight of solvents left in the vacuum oven dried carbon rod electric arc produced solvent extracted C60. See:

      Unfortunately these C60 solvent extraction producers mislead the consumer about the residual solvents left in the solvent extracted C60. They use the test method ASTM 8260 B which measures VOLATILE Organic Compounds. This only measures what VOLITILE compounds (solvent vapors) that come off from heating the sample after they vacuum bake the sample for hours. This measurement does not measure the solvents that are chemically bonded or physically trapped in the “dried” C60 powder. They are also misleading people using the word purity. They should be using the word “Ratio” of C60 to other fullerenes. They solvent (toluene is most common) extract the C60 form the soot produced from the carbon rod electric arc method. This carbon rod arc process randomly produces about 10% C60 and about 90% other various forms of amorphous carbon and other fullerenes. After the solvent extraction process they claim, by a spectral analysis (color comparison) they are left with a ratio of 99.99% C60 and 0.01% C70. Then they vacuum oven dry the most of the volatile solvents off. This is very misleading as this 99.99% refers to the ratio of C60 to other fullerenes and does not consider the bonded and trapped solvents, or the NON-volatile components of the toluene. Its like having 99 pennies and one dime in a slurry of solvents. That’s the 99.99% “purity” they claim. Then they dry the volatiles off. They again mislead people saying most all the volatiles are gone. But mention nothing about the trapped and bonded solvents. The more they dry it, the more crystalline it gets. For an analogy, it is like a mass of dried honey loaded with bb’s. This is why you can actually see the crystal clusters with the naked eye in their as purchased C60 powder. Then they grind these crystals and then mix these ground crystals in oil for 2 weeks or more in an effort to further separate these agglomerated crystals. Then they filter out the crystals that do not break down and some regrind these for the next batch.

      They get away with this as they are deceptive. As most people do not have the science background to discern what they are being told.

      Many prominent Carbon 60 producers refuse to sell C60 for human consumption, i.e., like Sigma Aldrich, Fisher Scientific and Nano-C.

      We, at Greska’s Carbon-60, do not use any solvents ANYWHERE in out process. We are the only ones who produce a truly food grade C60 for consumption. See our science pages at to back up our claims. Bob Greska
