You can use silicone as a substitute, but plumbers putty is simpler and far easier to clean up. 100% SILICONE
Silly Putty is made by Crayola of different types of silicone. It was created by accident when scientists were trying to make a cheap rubber substance.
Starting with ordinary silicone rubber sealant add as much ultra-fine graphite powder as it is possible to get the sealant to absorb to make a putty. You will need to add so much that the putty will *almost* no longer be mouldable. Form the putty around a wire and leave to cure. You will now have a carbon rubber electrode. If it does not conduct you have not added enough graphite dust. As some silicone sealant contains fungicide this should not be used on the skin. Adding lighter fluid to silicone sealant thins it down. It may be possible to do this when making the putty to thin it down and get it to absorb more graphite powder. However I have not attempted to thin the mix in this way and as the lighter fluid stays in the silicone putty after curing *never* use this when skin contact is intended.
Either, but there is usually a rubber washer supplied with the fitting that is better.
Silly putty is used by children who 'play' with it
It will not dry out and if the drain needs to be removed at some point, it can be. Glue would make it difficult to work on. Modern 100% silicone caulk will also work, and can be removed easily, like plumber's putty.
The difference between silicone oil and mineral oil are its structure and uses. Silicone oil is an oil made of semi-inorganic polymers. It is used in things like lubricants, adhesives, synthetic rubber and electrical insulation. It is also one of main ingredients in Silly Putty. Mineral oil is made from the distillation of petroleum. It is used in things like cosmetics, lotions, as a thermal fluid in electric components and as a laxative.
Normally you would use Plumber's Putty to seal the faucet to the sink. Some man made sinks can absorb the oil in the putty and darken in which case a bead of silicone caulking would work.
NO it can not
I have identified asbestos in both Putty and rubberised sealants
Silicone implants used for augmenting the female breast have a silicone rubber shell filled with a viscous silicone gel.
Oils from putty soak into and discolor marble. Putty not used when putting pipe together.
