The importance of salt in so many human endeavors cannot be overemphasized, particularly in the kitchen. It is hard to see any meal in the modern world that’s being prepared without salt. It is a spice that adds flavor and taste to meals.
However, considering how often it’s been used and how almost impossible we can’t do without it, especially in the kitchen, many people often wonder whether salt can catch fire. So, is salt flammable or even combustible?
Generally, salt is not flammable and cannot easily catch fire, except it gets to a temperature of 1470degrees Fahrenheit (800 degrees Celsius).
In this post, we talked about everything you need to know about the flammability of salt and salt water.

What is Salt?
Salt is a chemical compound comprised of both positively and negatively charged ions, which also create an electrochemically neutral compound.
But, for this article, we would be discussing the day-to-day salt we use in the kitchen as a tasty spice for our meals.
The domestic salt we use daily is called table salt, and its chemical name is sodium chloride. Sodium chloride, meanwhile, is the scientific name for the chemical compound of sodium and chlorine, which is given in the periodic table as NaCI.
The sodium that makes up this compound is positively charged, whereas the chlorine is negatively charged, which makes this compound electrochemically neutral.
Therefore, sodium chloride is seen as salt in the chemical sense and is also called salt in colloquial terms.
Salt exists in great quantities in seawater. The open ocean has about 35grams (1.2oz) of solids per liter of seawater, a salinity of 3.5%. Generally, salt is necessary for life, and saltiness is one of the crucial tastes humans can ever have or crave.
You can trace part of the evidence of salt as far back as 6,000BC when people residing in modern-day Romania boiled spring water to extract salts and traced back to China with their salt-works over the same period.
Table salt is what we use to season our foods, enhance flavors and preserve foods for longer.
Salt also contains iodine, which is an essential nutrient that we need for our health and wellbeing.
Meanwhile, excessive salt intake can cause cardiovascular illness like hypertension; hence, you should check your intake level. Back to the key question, is salt flammable?
Is Salt Flammable or Combustible?
Well, salt is not considered flammable or even combustible or easily catches fire and will not also start melting until it gets to a very high temperature of about 1,470 degrees Fahrenheit (800 degrees Celsius).
However, it is almost impossible for any salt in your home to be exposed to such temperatures; therefore, it cannot burn or explode.
Again, salt has such a high burning point because of sodium and chlorine, which form a very strong bond that produces a huge amount of energy, making it difficult to combust or explode.
That is why it’s very hard to break the bond, except it faces a severe amount of heat. Meanwhile, there are different types of salt around, and we’d be highlighting them to let us know which of them is disastrous, flammable or combustible.
Is Table Salt Flammable or Combustible?
As mentioned earlier, table salt is the type we use at home to spice up our food and other domestic usages and is chemically called Sodium Chloride (NaCl).
It is not flammable or combustible, and cannot melt, except it reaches 1,472 degrees F (800 degrees C).
Meanwhile, salt can only boil at 2,575 degrees Fahrenheit (1,413 Celsius) and so will not burn until it gets and remains hotter and break down into the individual chemical components.
However, you will hardly encounter such a high level of temperature in a real-life sense.
What Reaction Will Occur If You Throw Salt Into A Fire?
Any time you throw salt into a burning fire, you will notice that the flame from the fire has experienced a color change.
This is not because of the burning salt, but because the flame’s heat changes the energy of the electrons in the salt emits light photons. Hence, you will notice a yellow flame when burning salt.
After the fire must have gone down, you will find out that the salt didn’t burn at all, and you will only see it dwelling amid the ashes of the burnt materials. Salt rather than burn will even help to quench a fire.
Is Salt Water Flammable or Combustible?
Saltwater is similar to seawater. It is called saltwater due to the high levels of salt in seawater, and because of that, it is not flammable or combustible.
To buttress this point, try using it to quench a fire, and you will find out that it will readily serve that purpose.
It is not commonly used for firefighting because freshwater is preferable due to the high salt level in saltwater.
This isn’t because it can add to the burning flames, but because it can cause other disastrous effects and rust extinguishing tools. So, no water catches fire, whether salty or not. They can only do vice versa (extinguish).
Is Pink Salt Flammable?
There’s no difference between pink salt and table salt regarding their chemical compounds. In other words, like table salt, pink salt cannot be explosive.
Therefore, you don’t have to worry about using them while relaxing your baths with candles because they cannot catch fire.
Is Iodized Salt Flammable?
Just like other previously discussed salts, iodized salt is not flammable. Though it contains iodine chloride, it is difficult to break its components apart; hence, it cannot catch fire.
Is Rock Salt Flammable?
Also, rock salt, like its brothers, is not flammable. It is difficult to burn or combust; hence, you have nothing to worry about when using it to serve its purposes.
Generally, Is It Dangerous to Heat Up Salt?
Under normal conditions, it is not dangerous to heat salt because it has a high melting point and boiling point, so we can use it freely in our daily cooking without fear of causing any harm.
However, we should apply all safety measures wherever possible because prevention, they say, is better than cure.
