Glow Inc.
The Glow Inc. modification expands the possibilities of glow ink sacs obtained from glow squids, and also adds other interesting ink-related features.

Lumoball
Uses
By right-clicking, the Lumoball can be thrown to create a bright glow across the entire surface it hits.
The glowing trail looks great underwater and helps with better navigation during underwater exploration. Additionally, if the ball hits a living entity, it applies the Glowing effect to them.
Crafting
By default, shapeless crafting with two glow ink sacs yields 8 Lumoballs.
Pure Glowing Ink Container
Uses
This container can be converted into glowstone dust or used to refill the Ink Gun.
Crafting
Ingredients: Brewing recipe using a glow ink sac and empty bottles

Ink Gun
Uses
The Ink Gun allows you to shoot glowing ink over a greater distance than a regular throw, and holds up to 64 shots (1 shot = 100mb).
Refilling
The Ink Gun is refilled using Pure Glowing Ink Containers. When combined in the crafting grid, each container provides 400mb of ink.
Alternative method: holding Shift while combining the Ink Gun with containers in your inventory automatically uses them for refilling, while returning the empty bottles to you.
Crafting
Ingredients: 4 iron ingots, 1 copper ingot, and a bucket
