Experimental set-up to achieve directional solidification in a regular kitchen freezer. Depending on the freezer temperature and the insulation materials, either a planar or cellular front can be obtained. With a planar front, any bubbles initially present are repelled toward the bottom of the mould. A clear, bubble-free ice can thus be achieved in the upper part.
