Hairline cracks—tiny cracks in the surface—in porcelain sinks can happen due to age, chemical damage from cleaning products, dropping heavy objects on the sink, thermal shock from drastic temperature changes, stress during repairs, and manufacturing errors. Hairline cracks often start very small and grow longer and wider over time. While they may appear problematic, hairline cracks don’t indicate structural problems and may not impact the performance of sinks. However, they can eventually cause water leaks and mold growth if left to grow.
