Limitations of Soda Lime Glass
Struggles with Heat Changes
Soda lime glass can’t handle quick temperature shifts well. If it heats or cools too fast, it might crack or break. This happens because the glass expands and shrinks unevenly, causing stress inside. Borosilicate glass is better at handling heat changes because it doesn’t expand much. Soda lime glass isn’t good for things like lab tools or cookware that need to resist high heat.
For example, pouring hot water into a soda lime glass cup might make it break. It can’t deal with sudden heat changes, so it’s not used where heat durability is important.
Weak Against Chemicals
Soda lime glass can get damaged by chemicals over time. Moisture, acids, or alkalis can weaken it. Humidity especially causes tiny cracks to form and grow. Water reacts with the glass surface, making it less strong.
Scratches or hits make chemical damage worse. They create small openings where harmful substances can enter. The glass’s structure also has tiny gaps that let cracks spread. Below is a table showing how soda lime glass reacts to chemicals:
Problem Type | What Happens |
|---|---|
Water causes cracks to grow and weakens the glass. | |
Scratches or Impacts | Small openings let chemicals damage the glass structure. |
Surface Gaps | Tiny holes in the glass make cracks spread faster. |
These issues make soda lime glass less useful in places with strong chemicals, like factories or chemical storage.
Breaks Easily
Soda lime glass is fragile and not very strong. Its strength depends on having no flaws, but even small cracks can weaken it a lot. Big flaws lower its strength to 20–60 MPa, while tiny cracks reduce it to 60–200 MPa. This shows how its durability can vary.
Dropping a soda lime glass bottle can easily break it. Because it’s fragile, it’s not used in tough jobs like making airplane parts or car windows. Soda lime glass works well for simple things like bottles or windows but isn’t strong enough for harder tasks.
Not Fit for Tough Jobs
