Item #: SCP-XXXX

Object class: Safe

Special Containment Procedures: SCP-XXXX must be fully emptied, dried and sterilized before storage. Failure to do so may result in spillage of dangerous substances used during testing and/or unintended interactions with other SCPs.

Description: SCP-XXXX appears to be a ceramic vase with a floral motif, approximately 30 cm in height and 15 cm in width. Although its weight is consistent with a ceramic vase of similar dimensions, attempts to determine SCP-XXXX's composition remain unsuccessful; the object displays a level of durability that far exceeds what its appearance suggests.

Intermolecular forces remain constant inside SCP-XXXX, regardless of internal or external stimulus – ice does not melt at 0°C, liquid aluminum does not solidify at room temperature, etc. Matter resumes normal behavior once removed from SCP-XXXX. It is unclear whether the object maintains thermal equilibrium through absorption and emission of heat or some as-yet undiscovered means.

Intramolecular bonds are not affected by SCP-XXXX. It is still possible to create gaseous hydrogen and oxygen from liquid water via electrolysis inside the object, for example.

The same mechanism that affects matter inside the object also affects the object itself, rendering SCP-XXXX immune to its environment. During initial testing, SCP-XXXX was placed in an ice bath and monitored via thermal imaging. The object's internal and external temperature, remained fixed at 20.1 C. No condensation occurred inside the object, despite the control vase displaying considerable condensation under the same conditions, corroborating its resistance to external influences.

Even fully submersed in liquid nitrogen (-196.15 C), liquid tantalum hafnium carbide (3989.85 C) and liquid ████████████████████████████████████ (2.15 x 10^5 C) respectively, SCP-XXXX's temperature remained constant. The control vase shattered in the former test and vaporized in the latter.

Dr. ████████████ also tested how the object responds to extreme temperature differences by filling it with liquid nitrogen, which did not evaporate at ambient temperature once inside, and fully submersing it in liquid tantalum hafnium carbide. Heat transfer did not occur; Dr. ████████████ was able to pour the liquid nitrogen out of the object once the test completed, whereupon it began to evaporate.

SCP-XXXX also has exceptional compressive strength, withstanding pressures up to 790 Gigapascals. Testing will continue as new technology becomes available.
