— The basic feldspar recipe is X(Al,Si) 4 O 8, where X stands for Na, K, or Ca. The exact composition of the various feldspar minerals depends on what elements balance the oxygen, which has two bonds to fill (remember H 2 O?). Silicon makes four chemical bonds with oxygen; that is, it's tetravalent.
