Your problem is curing.
Silicone either needs moisture (the stinky stuff, smelling like vinegar) or time to cure.
Judging by the images, standard silicone would need weeks to properly cure.
You will be far better off getting some mold making rubber, silicone or similar from a hobby store or Ebay.
These are two components that you mix right before use.
Depending on the brandand type you have a work time of minutes to several hours, after that the curing starts.
Quick mixtures can be ready to be peeled in less than 6 hours.

If your aim is to get a replica of this glass then I suggest adding some support.
