Thermal Stress. One of the most common causes of hairline cracks on porcelain sinks is thermal stress. Considering porcelain is usually layered on metal (which conducts heat), the sink loses heat rapidly and can become very cold—even when the room isn't cold.
Heavy usage can result in cracks appearing or the unintentional dropping of a hefty object on the porcelain can chip off parts of the enamel. All these chips and cracks can be unpleasant to look at and might prompt you to want to replace the sink.
They can be caused by impact damage, heavy objects being dropped into the sink, or general wear and tear over time. Cracks are another common issue with ceramic sinks, and can be caused by a variety of factors, including impact damage, changes in temperature, or general wear and tear over time.
Every material will age over time. With that age, bathroom sinks can begin to show hairline cracks. To make your sink last longer, you should repair these hairline cracks as soon as you can.
Durable and long-lasting – With proper care, a ceramic sink can last for many years. The ceramic material is resistant to scratches, chips, and stains. Easy to care for – They can be cleaned with mild soap and water and do not require any special cleaners or sealants.
Porcelain is considered the hardest clay available today and it starts out as... ceramic. It is heated in a kiln at an extremely high temperature (higher than ceramic), so it is less porous and dense. Porcelain is very strong with a smooth finish.

Small or hairline cracks are usually nothing to worry about.
Slight — minor cracks between 1mm and 5mm in width, which can be fixed with filler. You might need to repoint exterior cracks. Moderate — cracks between 5mm and 15mm may need professional building work and there might be underlying repairs.
Hairline cracks of less than one millimetre in width or slight cracks of between one and five millimetres are generally not a cause for concern.
Abrasive tools: Abrasive tools like scouring pads and steel wool could cause unsightly scratches to form on porcelain sinks. Abrasive cleaners: Abrasive cleaners that contain harsh chemicals can stain, scratch, or damage the finish on porcelain sinks.
