Abstract
A calculation shows that convection provides slight stability to the morphology of a pure substance growing in an under-cooled melt provided that the surface tension is not very small or if the under-cooling is very small. A surprise of sorts turns up when gravity is reversed and the liquid melt acts like it is heated from above for here the perturbed convective fields destabilize the interface further moving the critical wavelengths to smaller values.
