question: Is glass sharp enough to hurt ants, if ants would walk on broken glass?
comment: For something sharp to make a cut, it also takes force to separate the material it's cutting into. So long as the weight of the ant focused on the sharpest point of any object is less that the force required to separate the cells holding them together, tye ant will be fine. And since they're basically weightless, they don't have anything to worry about.
passages: "Myrmecia" ants are frequently encountered by humans, and avoiding them is difficult. Wearing closed footwear such as boots and shoes can reduce the risk of getting stung; these ants are capable of stinging through fabric, however. A risk of being stung while gardening also exists; most stings occur when someone is gardening and is unaware of the ants' presence. Eliminating nearby nests or moving to areas with low "Myrmecia" populations significantly decreases the chances of getting stung.

   The banded sugar ant is considered a household pest and is occasionally seen in houses at night, capable of damaging furniture and fittings by chewing the wood; carbon disulphide is used to treat and remove a banded sugar ant nest. These ants do not pose any threat to humans, as they are incapable of stinging and can only spray formic acid, however, the larger soldiers are capable of inflicting a painful bite with their powerful jaws, and the formic acid they spray is corrosive to human skin. The eggs of this species were consumed by the Australian Aborigines.

   BULLET::::- In a Belgian study from 2015, 23 out of 24 adult ants scratched at small blue dots painted on their clypeus (part of their "face") when they were able to see the dot in a mirror. According to the published results, the ants were individually tested and were from three species, "Myrmica sabuleti", "Myrmica rubra" and "Myrmica ruginodis". None of the ants scratched the clypeus when they had no mirror to see the dot. None tried to scratch the blue dot on the mirror. When they had a mirror and a brown dot similar to their own color, only one of thirty ants scratched the brown dot; researchers said she was darker than average so the dot was visible. They also reacted to the mirror itself. Even without dots, 30 out of 30 ants touched the mirror with legs, antennae and mouths, while 0 of 30 ants touched a clear glass divider, with ants on the other side. Ants a few days old did not react to the dots. These three species have limited eyesight, with 109–169 facets per eye, and the authors suggest doing tests on ants with more facets (some have 3,000) and on bees.

   Within a few years, the Ants had taken over the entire South America. The weapon of mass destruction that they used was a suicide bomb. They also used advanced technological weapons, for example, the Ants used a kind of searching, powerful light, somewhat green in colour that took away human sight in an instant. 
   For ultramicrotomes, glass and diamond knives are required, the cut breadth of the blade is therefore on the order of a few millimetres and is therefore significantly smaller than for classical microtome knives. Glass knives are usually manufactured by the fracture of glass bars using special "knife-maker" fracturing devices. Glass knives may be used for initial sample preparations even where diamond knives may be used for final sectioning. Glass knives usually have small troughs, made with plastic tape, which are filled with water to allow the sample to float for later collection. Diamond blades may be built into such an existing trough, allowing for the same collection method.

   Some ants are also rated at a Pain Level 3, including the giant bull ant and the Maricopa harvester ant. Schmidt considered the sting of the Maricopa harvester ant as having a pain level of 3, describing it as such: "After eight unrelenting hours of drilling into that ingrown toenail, you find the drill wedged into the toe."

   Bulldog ants, from the genus "Myrmecia", are native to Australia, with all but one of the ninety or so species found on the continent. Belonging to the ant subfamily Myrmeciinae, they are among the most primitive extant ants in the world. This species is known to cause some fatalities in sensitive humans.
  
  Bullet ants, from the genus "Paraponera", are found from Nicaragua southward to the Amazon Basin. They are and close relatives of the genus "Dinoponera", which are New World ponerines known for their painful stings.
   Among ants, 23 of 24 adult ants, from three species, scratched at small blue dots painted on their fronts when they were able to see the dot in a mirror. None of the ants scratched their fronts when they had no mirror to see the dot. None tried to scratch the blue dot on the mirror. When they had a mirror and a brown dot similar to their own color, only one of thirty ants scratched the brown dot; researchers said she was darker than average so the dot was visible. They also reacted to the mirror itself. Even without dots, 30 out of 30 ants touched the mirror with legs, antennae and mouths, while 0 of 30 ants touched a clear glass divider, with ants on the other side.
   In January 1777, Captain Cook's ships HMS "Resolution" and HMS "Discovery" landed at Adventure Bay, Tasmania. On 30 January, William Anderson, a surgeon and naturalist aboard HMS "Resolution", wrote of two "troublesome" insects of Tasmania, one being the mosquitoes and the other "a large black Ant whose bite is almost intolerable for the short time it lasts". The ants stinging Anderson were almost certainly "Myrmecia esuriens".
   Small bench-top fires in laboratory spaces are not uncommon. Large laboratory fires are rare. However, the risk of severe injury or death is significant because fuel load and hazard levels in labs are typically very high. Laboratories, especially those using solvents in any quantity, have the potential for flash fires, explosion, rapid spread of fire, and high toxicity of products of combustion (heat, smoke, and flame)

   Measurement of the pH of glass surfaces is particularly important if glass objects have a matte surface, or have been exposed to kaolin or other substances. In the case of extremely small objects such as glass beads, pH measurement may be necessary to determine whether alkaline salts are present and changes in the glass are occurring.

   Devin Fore has read the prevalence of the nanoscale in the novel as a prescient shift of emphasis from an anthropocentric mesoscale to the a-human, microscopic scale of the insect, constituting a meditation upon "the cultural and anthropological challenges that would attend this process of technical recalibration."
