Avoid Sudden Temperature Changes: Sudden exposure to extreme heat or cold after being at high temperatures can cause porcelain cups to crack. Therefore, be cautious to prevent rapid temperature fluctuations.

Avoid Scratching: Using hard objects such as metal knives, forks, or other sharp tools to scratch the surface of porcelain cups can result in scratches or damage, affecting both aesthetics and longevity.

Regular Cleaning: Promptly clean porcelain cups after use to prevent the accumulation of stains. Avoid using abrasive cleaning tools or harsh detergents, as they may scratch the glaze surface.
