What is this collecting on the inside of my starter bottles?

Hello,

I am interested in the science of brewing :eek:

I am wondering what these particles that has started to collect over the rim are :)

Hope somebody knows the answer :)

Looks like nothing to worry about, probably just some tiny bubbles. What is plugging the hole of the erlenmeyer flask or glass jar you are using?
 
Looks like either the start of a krauzen, or the remnants of a krauzen, depending on where in the starter process you are...in other words, it looks normal to me.

:mug:
