One common type of oil seal is the lip seal, which features a flexible lip that makes contact with the rotating shaft to create a tight seal. Lip seals are often used in automotive engines, gearboxes, and industrial pumps due to their effectiveness in preventing oil leaks. Another popular option is the mechanical seal, which uses a rotating element to maintain constant contact with the shaft, ensuring a reliable seal even at high speeds and pressures.

Another significant advantage is the longevity of cast iron cookware. A properly maintained cast iron dosa pan can last a lifetime, often being passed down through generations. The more you use a cast iron pan, the better it becomes, developing a naturally seasoned surface that enhances its cooking properties. This durability also makes it a worthy investment, as you won't find yourself replacing it every few years like you might with cheaper, non-stick alternatives.

Beyond their decorative appeal, enamelled cast iron pumpkins are also functional. Many of these beautifully crafted pieces come with a hollow interior, allowing them to serve as storage for small items—be it candies during Halloween or knick-knacks throughout the year. Their sturdy construction makes them suitable for indoor or outdoor use. Imagine a group of these pumpkins lining your front porch, welcoming guests and trick-or-treaters alike, all while enduring the elements with grace and resilience.
