Per 
Special Containment Procedures: SCP-XXXX is to be contained in a standard secure locker in Site-45. No liquids or pastes with viscosity between 120,000 and 7,500,000 cPs are to come within 600m of SCP-XXXX unless contained within an airtight receptacle with walls consisting of at least one cm of lead. In case of containment breach, all travel to and from Site-45 is to be suspended until all instances of SCP-XXXX-1 are found and incinerated as per Protocol Einfugen-1. If breach is suspected to extend beyond Site-45, MTF Lambda-7 "Jif Hunters" is to be deployed and D-Class personnel acquired to perform Protocol Einfugen-2. Dispose of all affected D-Class personnel by incineration.
Description: SCP-XXXX is a Ball mason jar of peanut butter, measuring 16oz in volume. While carbon-dating attempts to date SCP-XXXX's creation have failed, the unique Ball script logo suggests the jar was manufactured between 1892-1896.
The peanut butter within SCP-XXXX exhibits all expected behavior of peanut butter excluding the natural process of separation of oil, which has not been observed to occur. Any amount of SCP-XXXX removed from the jar immediately replenish, leaving a flat surface. When a portion of SCP-XXXX comes into contact with any carbon-based substance, with the exception of ██████ branded white sandwich bread, it becomes SCP-XXXX-1, an adhesive with no known failure points. All stress tests performed on SCP-XXXX-1 have resulted in failure of the adhered material, rather than SCP-XXXX-1. SCP-XXXX-1 is rendered inert and non-anomalous after exposure to direct heat of at least 3,400°C for a sustained burn time of 23 seconds.
In addition, if a substance of a measured viscosity between 120,000 and 7,500,000 cPs in contact with a carbon-based substance comes within 250m of SCP-XXXX or SCP-XXXX-1, it will transform into SCP-XXXX-1 over the course of 2.3 seconds, adhering to the current surface(s) it is in contact with and further extending the radius SCP-XXXX can affect. This effect does not occur with every substance between the viscosity levels. Observed exceptions include human feces, multiple varieties of peanut butter, and ███████.
If SCP-XXXX is removed from its container and spread onto ██████ branded white sandwich bread, it fails to exhibit anomalous properties. If this combination is formed into a sandwich and consumed by a living human, all current instances of SCP-XXXX-1 within 10 miles of the consumer lose all adhesive properties and become inert, non-anomalous peanut butter. Within two hours, the consumer will begin to exhibit symptoms of hypertension, and blood pressure will rise to roughly 200/130 before all liquids in the body are converted to SCP-XXXX-1, resulting in instant death.
SCP-2318 was brought to the Foundation's attention on ██/██/19██ after a home in the United States countryside near ██████, Kansas reportedly collapsed, crushing a family of five that had just moved in to the abandoned home. Upon examination, the home had seemingly been constructed using solely SCP-XXXX-1 as a means of assembly. A human male affected by SCP-XXXX was recovered in the basement along with SCP-XXXX, next to several shelves of other foods, all canned between 1876 and 1894. No anomalous properties have been discovered related to said foods, and all have been deemed non-anomalous and disposed of.
Incident Log XXXX-1: On December 12, 20██, Dr. Alex Wilder failed to recall the gel implants in his shoes and ventured within SCP-XXXX's influence area. The implants instantly hardened, causing Dr. Wilder to trip and fall. The expanded influence range caused by the creation of this instance of SCP-XXXX-1 spread throughout nearly half of Site-45, causing two containment breaches and ██ injuries, as well as almost 12 million USD in damages to Foundation equipment. After Incident XXXX-1, containment procedures were updated to add a contamination buffer of 350 meters, to prevent an Ekhi-scale contamination event.
