it should be stable and should be volatile in nature.
Yes, you can. Use workable fixative or retouch varnish.
Hair spray is a pretty good substitute.
You should only use hairspray on work you don't intend to keep as it will make pastel brittle and it will yellow the paper over time. If you are experimenting with pastel and just doing quick sketches that you will work up into a proper painting later on then yes use cheap hairspray .If you are working on something you intend on exhibiting or selling I would invest in proper fixative to keep your colours true for longer and avoid unhappy buyers of your work.Ask yourself this question would you use pastel fixative on your hair ? No they are designed to do different things.
tie them together and hang them upside down. after they've dried, there is floral fixative u can spray them with to keep them from falling apart.
All cooking salts are salty, not all salts are. Gipsum is a salt, but has no discernable taste at all. It is so bland that it is used as a filler and bulker in some food items, and its natural fire resistant properties make it perfect for drywall.
Yes, you can. Use workable fixative or retouch varnish.

Fixatives are classified as coagulative fixatives and cross-linking fixatives. Carnoy's fixative is a coagulative fixative. Coagulative fixatives change the shape or structure of protein molecules without binding to them, while cross-linking fixatives bind chemically to protein molecules at one or more points. In cross-linking fixatives molecules are linked together to form an insoluble latticework by forming chemical bridges between protein chains. Carnoy's fixative is a coagulative fixative.

Picric acid is a fixative (for example is found in Bouin's) but can be found in picrosirius red (is required for the sirius red stain to selectively bind collagen).
methyl alcohol

Carnoy's solution is a fixative creating covalent chemical bonds between proteins in tissue. Most commonly used fixative in histology is formaldehyde. It prevents decay.
Expoxy resin is very stable and that is exactly what you need in a goo fixative. The last thing you need is an unstable mix of chemicals,that can end in disaster. The advantages of epoxy resin as a fixative are that it is durable, long-lasting, and inexpensive. Epoxy resin also resists cracking, unlike many older adhesives.
Charcoal drawing can be made more permanent using a spray fixative. Most craft stores carry one or more brand-name of fixative. I recommend you try a test, using the spray on an unimportant scrap of paper with charcoal on it, as sometimes there is a change in colouration when using fixative and it is best to know what to expect.
