Can someone tell me why this is fragmented inside?

I found this brown piece at the tide line in Cayucos Ca this past week.

Fragmented or fractured inside
by: David & Lin @ OdysseySeaGlass

This happens when glass has been superheated in a bonfire and then had water thrown on the bonfire.

The rapid cooling shrinks the glass and causes fracturing.
