Place an empty or partially filled Javelin mold into the slot to fill it with metal from the vessel. It takes 100 units of metal to completely fill an empty Ceramic Mold. The text in the vessel's GUI will be updated to show the amount of metal remaining in the vessel.

Unshaped Ingot
To fill the Javelin mold from a ceramic ingot mold, right click the liquid unshaped ingot to open the casting interface:
Put the ceramic Javelin mold in the second input slot and wait for the filled mold to finished.
Javelin Heads can also be crafted by using ingots on an anvil with a hammer. This is the only option for higher tier metals that cannot be cast. The durability depends both on the metal used and the skill of the smith forging the tool.
The Javelin, though capable of being used as a melee weapon, is more effectively used as a throwing spear. It is the most only dedicated weapon which can be made without metal. The Javelin can be drawn like a bow, making it a ranged weapon which inflicts Piercing Damage on players and mobs that it is used against. The javelin passes through enemies and can be recovered by picking the item up off of the ground or block it was stuck into. There is a chance it will use durability when thrown.
