Abyssalite is a very strong solid element in the Miscellaneous category and is found in large veins separating Biomes. It acts as a natural thermal insulator, preventing heat exchange between biomes as long as the abyssalite boundary remains intact. In order to mine abyssalite, a duplicant must possess the Superhard Digging skill. Abyssalite cannot directly be used as a construction material, but can be combined with Reed Fiber and the Rare Resource Isoresin inside a Molecular Forge to create Insulite, which is an extremely similar material that can be used in construction.

Usage[]

Molecular Forge can produce Insulite from Abyssalite, Isoresin and Reed Fiber:

15 kg Isoresin + 80 kg Abyssalite + 5 units Reed Fiber = 100 kg Insulite.

Abyss Bugs can eat Abyssalite.

Abyssalite melts into Liquid Tungsten.

Thickness of Abyssalite Veins[]

Naturally spawning Abyssalite veins are generally at least two tiles thick. Two tiles are the minimum thickness that is necessary to insulate heat due to the mechanics of Thermal Conductivity. With only one tile, materials on either side can impart and draw heat at just over half of their own thermal conductivity.

When excavating Abyssalite, especially those surrounding Volcanic Biomes, care should be taken not to thin out the seams too much. It is good practice to check the Temperature Overlay when doing so. Because of Flaking, hot Abyssalite tiles can instantly evaporate liquids, completely ignoring its low thermal conductivity.

Trivia[]

Abyssalite is named Katairite in game code.
