The shrinkage or gloss of the part of the wall thickness is because the surface layer does not form a solid curing layer.
When the center shrinks, the surface will be pulled inward into the shrinkage hole, and even the heat from the inside out will melt the surface layer again and the gloss will appear.

Why the molten rocks cools slowly below the earth surface as compared to surface?
Rock is an excellent insulator, meaning that it loses heat slowly and gains it slowly, so an intrusion loses its heat slowly to the country rock, and the country rock absorbs it slowly (some of it undergoing metamorphosis). This means that the rock under the surface cools very slowly. On the surface, water and air cause the heat on the surface of the rock to cool very quickly, forming an noticeable chilled margin. This means that in a lava flow, for example, the surface cools to form something that looks solid, whereas underneath it can still be flowing. Inevitably the lava underneath will cool too, and more quickly than underground, as it is nearer to the cool atmosphere.
