Why are there floating things in my starter?

I've made a few starters now each time using 100grams of Extra Light DME from AHS. I put a little water in my flask (have tried cold and warm) and fill it up to 1L. I mix it all up and it looks fine. Turn on the heat, about medium, gets to about 150 and then I get this coagulation that won't go away, even after it's cooled. I'm sure it's clean and sanitary after being heated for awhile, but it's pretty ugly!

Is this normal??

Just looks like yeast in suspension to me.

Have you tried heating the water first and then mixing in the DME? It could be un-mixed DME. Those specks are too big to be yeast in suspension especially since the wort is starting to clear. Did you add the yeast already in that picture? I am guessing no especially since their is a vial of White Labs in the background.

This is before adding the yeast. Yeast is still in vial in the background.

Yes, I've tried both cold and warm water. It dissolves fine at first and then these chunks appear after heat is applied.

That is hot break. It's totally normal. RDWHAHB

Yeah, I missed that part...

+1 on hot break, you'd see the same thing if you had a big glass brew pot...

That would be cool. A 10-gallon Erlenmeyer.
