Why Water Glassing Works

How Water Glassing Locks In Freshness

Water glassing is a timeless method that has been used for centuries to preserve eggs. By submerging eggs in a solution made from water glass, also known as sodium silicate, you can extend the lifespan of fresh eggs for several months.

But how does water glassing work? Let’s explore the science behind this fascinating preservation technique.

The Science Behind Water Glassing Eggs

  • When eggs are fresh, they have a protective coating called the bloom. This natural barrier helps to keep out bacteria and moisture, preserving the integrity of the egg.
  • Water glassing works by creating an artificial bloom on the eggshell surface. The water glass solution is alkaline, which raises the ph level, making it difficult for bacteria to survive.
  • Submerging eggs in the water glass solution forms a thin, protective layer that acts as a barrier against bacteria and air. This prevents oxygen from penetrating the eggshell, slowing down the deterioration process.
  • The water glass solution also helps to seal the pores of the eggshell, reducing the chances of bacteria entering. This further extends the freshness and shelf life of the eggs.
  • Unlike refrigeration, which requires a constant cold temperature, water glassing allows eggs to be stored at room temperature. This makes it a convenient preservation method, especially in areas with limited refrigeration facilities.

With the science behind water glassing eggs explained, it’s clear to see why this method has stood the test of time. By creating a protective barrier against bacteria and air, water glassing locks in the freshness of eggs, allowing them to be stored for extended periods.

So the next time you find yourself with an abundance of fresh eggs, consider water glassing as a sustainable and effective method to ensure you have a supply of eggs for months to come.
