Lead, because of its toxicity, can often times be harmful for humans as well as the environment. The fumes created by the led during the glass making process can also be hazardous as well, creating a dangerous work environment. Kinari Glass wanted to change this; so, we created out our own. We created a highly water-resistant, sustainable, lead-free glass titled “C-Series”, which was patented in 2011. The C-Series glass was created to ensure the longevity of our product, as well as keeping the quality high at reasonable prices
