Obsidian does not have cleavage because of the way it forms. Obsidian is essentially nature's form of glass and so it has no regular or patterned crystal structure. Without that crystal structure, there is no cleavage.
Chalcopyrite does not have cleavage. It typically exhibits a conchoidal fracture instead of cleavage planes.
Olivine does not have cleavage. It exhibits a granular or irregular fracture pattern instead of cleavage planes.
No, ice does not have cleavage. Cleavage is a property of minerals, not ice. Cleavage refers to the way a mineral breaks along planes of weakness, which is not applicable to ice.
Lead does have cleavage. Specifically, lead-induced cleavage is an integral part of ribosomal RNAs, and performs at a neutral pH.
Corundum has a basal cleavage, meaning it cleaves parallel to its basal plane. This cleavage is often poor and can be difficult to observe.

Sulfur's cleavage is imperfect.
They have an obsidian nearby for Catal Huyuk and for Jericho they already have imported obsidians.
