Crafting a Krypton Lamp
Krypton Lamp is crafted from Krypton Gas using a crafting_shaped recipe. It is one of four noble-gas lamps available in the registry.
Handling Krypton Gas
Krypton Gas is transported in a Krypton Gas Bucket. Leave the bucket as a bucket until you are at a crafting grid. Placing it in the world turns it into a Krypton Gas block, which is not what you want if the goal is a lamp.
Running the Recipe
At a crafting grid, arrange the Krypton Gas input according to the shaped recipe to receive a Krypton Lamp. The gas is consumed. The resulting lamp can be placed as a light source wherever you need it.
Related Lamps
Argon Lamp, Helium Lamp, and Neon Lamp are made the same way from their respective gases. If you have several noble gases stored, you can produce a full set of lamps in one crafting session. Keep each gas bucket labeled or in its own chest slot so the shaped recipes do not get confused. When a lamp is placed, the gas is gone; gather more Krypton Gas to make another.
