Boxed Chemical Stack

Boxed chemical stacks follow the same format as any of the chemical stacks (gas, infusion, slurry, or pigment) but they have an extra helper tag called to chemicalType inside the block to specify the type of chemical being deserialized. Eventually this might be changed to be automatic. The valid chemical types are:

• gas
• infuse_type
• slurry
• pigment

For example a Boxed Gas Stack would look like:

{
  "gas": REGISTRY_NAME,
  "amount": long,
  "chemicalType": "gas"
}
