This optional integration adds support for Mekanism chemicals in various Refined Storage components, allowing storage, transfer, viewing, and autocrafting with chemicals.
## Chemical storage
Chemical storage blocks and disks allow you to store chemicals in the storage network. Each tier has a specific capacity:
| Tier | Disk | Block |
|----------|----------------------------------------------------------------------|------------------------------------------------------------------------|
| 64B |

64B Chemical Storage Disk |

64B Chemical Storage Block |
| 256B |

256B Chemical Storage Disk |

256B Chemical Storage Block |
| 1024B |

1024B Chemical Storage Disk |

1024B Chemical Storage Block |
| 8192B |

8192B Chemical Storage Disk |

8192B Chemical Storage Block |
| Creative |

Creative Chemical Storage Disk |

Creative Chemical Storage Block |
- **64B** stores 64 buckets of any chemical
- **256B** stores 256 buckets
- **1024B** stores 1,024 buckets
- **8192B** stores 8,192 buckets
- **Creative** stores an infinite amount of buckets
They support uncrafting and upgrading like any other storage disk.
## Importer
The [Importer](https://refinedmods.com/refined-storage/input-and-output/importer.html) supports extracting chemicals from external chemical tanks into the storage network.
## Exporter
The [Exporter](https://refinedmods.com/refined-storage/input-and-output/exporter.html) can insert chemicals from the storage network into external chemical-compatible machines or tanks.
## External Storage
The [External Storage](https://refinedmods.com/refined-storage/storage/external-storage.html) can connect to Mekanism chemical tanks, allowing them to act as external storage for chemicals.
## Storage Monitor
The [Storage Monitor](https://refinedmods.com/refined-storage/viewing-resources/storage-monitor.html) can display the amount of a configured chemical in the storage network.
## Autocrafting
You can autocraft chemicals by using [processing patterns](https://refinedmods.com/refined-storage/autocrafting/pattern.html#_processing_patterns) that define chemical inputs and outputs. The [Autocrafter](https://refinedmods.com/refined-storage/autocrafting/autocrafter.html) will insert chemicals into compatible machines, and expect the output chemicals to be returned to complete the task.
