Blank is an internal IC2 Experimental placeholder item with no EU, no GUI and no survival recipe.
Field guide
Press the NEI or JEI search field and type `blank`. The Blank entry appears under the Industrial Craft 2 mod section.
Hover over the item: Blank shows no EU capacity, no tier, and no usage recipes, which is the signature of a placeholder.
In creative mode, scroll the IC2 tab. Blank sits among unfinished or internal variants and has the default texture.
Continue your normal IC2 progression — rubber tree, Tin Cable, Generator and LV Macerator — without trying to craft or place Blank.
