What happens if you put glassware in the dishwasher and it is not dishwasher safe?

If you place non-dishwasher safe glassware in the dishwasher, it may become damaged due to high temperatures, harsh detergents, or the force of water and other items moving around. This can lead to chips, cracks, or even shattering of the glass. Additionally, any special coatings or finishes on the glass may be compromised. It's generally best to hand wash delicate or non-dishwasher safe glassware to ensure its longevity.
