Description

SCP-5907 is a 19th-Century oil lamp comprised of a small oil chamber and a wick consisting of hemp and cotton. Igniting the wick causes SCP-5907 to emit trace amounts of fluctuating Akiva radiation.
After approximately 30 seconds, SCP-5907 starts releasing smoke; with inhalation causing transfiguration of human tissue into synthetic cotton-like material and calcium-heavy bio-matter such as bones into aluminum.
There is no known method of terminating the transmutation.
Discovery
On 2020/02/23, the Foundation received a police file containing information on severely mutated human corpses, including several photographs. Foundation Agents were deployed to the residence where the corpses were located, which was still under police investigation.
SCP-5907 was discovered due to its abnormal levels of Akiva radiation, detected by investigators' GADs1. It was located in the room of William Corbin, the son of the residence's owner. The bodies of William, Veronica, and Fresco Corbin were all located in the room. A video file was also recovered from William's personal computer.
Cover story TT31 (Carbon Monoxide Leak) was enacted to explain the deaths of the Corbin family; all three corpses as well as SCP-5907 were relocated to Site-51. All mentions of the corpse's mutation were removed from police records and all emergency responders were amnestisized to remove memories of the incident.
The Investigation Team attempted to locate the pawnshop described in the video, but public records indicate no such store has ever existed in the area.
Incident Report

On 2020/03/25, the three corpses were being moved from Biohazard Observation Chamber-3 to their permanent storage location in Safe Storage Locker-59. Upon being lifted, the corpses shed their outer layers, which formed a total of three denim jackets, six denim gloves, three pairs of denim pants, six denim socks, and three denim gimp masks. Aside from their creation, the clothing is non-anomalous. Underneath the corpses' layers of clothing were only skeletal remains and cotton stuffing.
The Corbin family's skeletons were incinerated and the remaining clothing has been folded and stored within SCP-5907's containment locker.
