Basalt | Properties, Formation, Composition, Uses

Basalt is a type of volcanic rock that is formed from the solidification of molten lava. It is an igneous rock, meaning it is formed through the cooling and solidification of magma or lava. Basalt is one of the most common rock types on Earth, and it can be found in various locations around the world, both on land and under the ocean floor.

Safest Cookware Materials (and What to Avoid)

This type of stainless steel (also labeled 18/10 or 304 stainless steel) is extremely durable, resists corrosion, and only leaches trace amounts of nickel and chromium. Note that you should NOT cook highly acidic foods in stainless steel cookware, as these foods can cause more metals to leach into your food.

Thanks to all the scientists, researchers, universities, government departments and investigative journalists for making this data possible and available.

Is Stainless Steel Cookware Safe? (Latest Research)

Can chromium or nickel leach into my food? Studies prove that small amounts of chromium and nickel can leach into food when cooking with stainless steel pots and pans. While the amount depends on what you cook (acidic versus non-acidic foods), the length of cooking time, a used or unused pan, and other factors, no levels of …

Although basalt-derived paddy soils contain high Cr levels and pose serious environmental risks, the mechanisms controlling Cr transformation during a…

Chromium leaching vs. oxidation state for a contaminated …

When applying S/S treatment to chromium contaminated soils it might be assumed the chromium would be physically entrapped in the matrix and therefore not subject to leaching during the TCLP test. This study shows, however, that this is not the case and that chromium will leach from a S/S treated sample if it is in the hexavalent form.
