I have an idea for a safe class SCP.
It appears to be a standard oven, although it cannot be damaged. When an object is baked in it, said object becomes sentient or even sapient. The complexity of the consciousness is based on how complex the object baked is (EG. Loaf of bread equals a dog, cupcake equals a primate, cake equals a human). It would be possible to "interview" these objects with some kind of neural interface, or perhaps one of the SCP's which can read thoughts.
With regards to containment procedure, nothing special required. Just that it be locked in a room.
For how it came to foundation attention, I was thinking that it be recovered from a destroyed bakery. The baker would have attempted to bake something far more complicated than a cake, and botched it. The advanced consciousness then destroyed itself and the bakery in rage.
Any advice on how I can improve this would be appreciated.
