- Engineered stone became popular in the 2000s as a durable and more affordable alternative to natural stones like marble and granite for making benchtops.

A Filipino stonemason named Ronnie Ponggos was diagnosed with chronic silicosis, an incurable lung disease.
It is caused by inhaling fine silica dust from cutting and processing stone benchtops and tiles commonly found in kitchens.
