Approx. 2-1/2 oz crucible is just deep and wide enough to tin most small parts and wires, yet small enough to heat up quick and reduce the amount of solder required by most other pots...including our own. Grey Cast iron crucible is chemically stable and highly resistant to the corrosive nature of soldering with higher tin contents, making this pot perfectly suitable for Lead-Free Soldering. Only 5 Minutes to Take Solder from Room Temperature to a Liquified State
