Honey crystallization as an analogue for magma segregation and cumulate textures

Maybe I’ve got low blood sugar, but I think I see a magma chamber in that jar of honey.


There is clearly some crystal settling going on there, and it appears that the more crystals there are, the easier it is to trap bubbles. When the clots of crystals get too dense, they peel off (stope) and drop down to the floor of the jar. Similar sorting of minerals by (a) crystallization sequence and (b) density occurs within crystallizing magma chambers. I’m not sure where the bubbles fit into this analogy – perhaps they are low-density minerals, or miarolitic cavities?
