Molten Channel transports Molten products. Molten channel can not be built sloped, but can be built in 4 different heights, allowing to cross shallow valleys. Molten transports do not have a Sorter-type building, but do have Molten Balancer. Also there is no external Storage Building for Molten products, therefore the best way to store Molten products is in long channels. Molten Channels can not be upgraded.
