** In general, you simply cannot. If the fuse has no markings and the
fuse wire is vaporised all you have is a glass tube with end caps.
However, a blown fuse is not much use to anybody so the point is moot. What
you may importantly need to know is what sort of fuse to replace it with.
For that, you need to consider the application, examine any markings on the
equipment that indicate fuse type and rating plus use a bit of electronics
It is very risky to assume the fuse that you find in something ( whether
blown or not) is the correct type.
Others may well have been there before you and tampered or the factory may
even have installed the wrong type.
I see it all the time in service work - I now have a nice collection of
25, 30 and even 50 amp fuses recovered from gear that required no more than
a 2 amp fuse.
Now, if you would like to come back with details of the SPECIFIC question
you ** REALLY ** needed answering - maybe I can help.
the answer to your last question is not "no" but a "kind of a yes"
But then you may as well not have a fuse there to protect your electronics
or wiring why not just short out your fuse holder.
If it is a fuse for the house wiring why not just save time and anxiety,
just burn your house down to the ground
Also, when replacing a fuse, can the amperage be higher?

If the OP specified what the fuse was for, it might just make life a little
As for ridiculous sized fuses, I've come across it before, most common I've
seen is person X owns a 12v regulated PSU for radio/tv whatever, buys
multiples of fuses at a hit, rated at 20 or so amp 250v, takes them home and
sticks then in the 12v and 240v sides, not thinking it only takes a few amps
at 240 to get their 20amp 12v.
