Why blow warm air before puting in a mute?

kehaulani

You know, I was blowing warm air into my trumpet yesterday, before putting a mute in, and it hit me. Why am I doing this? I've been doing this since the 50s by rote and never questioned it.
Why?

The moisture from the warm air gives more grip to the cork making it stay in the bell more securely.

Condensation helps mute corks grip the bell.

I only fog the bell when using the Jo Ral bubble mute, as that's the one that has the greatest tendency to fall out (for me, at least).

Other mutes get a dusting of violin rosin on the corks.

But, once the cork returns to it's original shape, wouldn't the mute fall out of the horn?

Often done for bubble mutes, since most of them have a tendency to fall out.
Unless you use a bubble mute without cork, like the Soulo Mute bubble version.
Never had an issue with that one falling out
