Cast Iron Teapot Health & Safety
When you decide to purchase a cast iron teapot, you assume it is safe to use. But, these days, there are countless companies making Tetsubin style teapots from around the world.
How do you know the teapot's lining won't leach heavy metals, including lead? There are multiple ways that heavy metals can leach from the ceramic lining. If it wasn’t applied appropriately to the interior of the teapot, if the porcelain enamel liner itself was not formulated correctly or what if it was not fired at the appropriate temperature or for the necessary length of time?
In most cases, we have to simply trust. And that's not good enough.

Why Japanese Iwachu Iron Teapots are Safe
Japanese made Iwachu cast iron teapots provide certified laboratory testing reports authorized by Japan’s Ministry of Health (February, 2021). These teapots were tested using a standard laboritory leaching method to detect Cadmium, Lead, Mercury and Chromium, some of the most common heavy metals to cause human poisoning. These contaminents are usually absorbed through water, food and air.
The lab results pictured below show none of these heavy metals, including lead, were detected.
The English translation of the lab report and the original lab report in Japanese are displayed below.
