Cut the excess foam (or wood) from the surfboard blank using the jigsaw. Be sure to leave 1 to 1 1/2 inches (2.54 to 3.81 cm) excess from the surfboard template trace; this will give you room to shape without catastrophic error. 1  Saw with extreme caution, especially when cutting around the stringer on the nose.
In chemistry, a vanadate is a compound containing an oxoanion of vanadium generally in its highest oxidation state of +5. 4 anion, which is present in e.g. sodium orthovanadate and in solutions of V2O5 in strong base (pH > 13 ).
History of Vanadium Vanadium was thought to have been first discovered in 1801 by Spanish scientist Andres Manuel del Rio, but he discovered chromium in brown lead ore. In 1831, Nil Gabriel Selfstrom, a Swedish scientist, discovered Vanadium in iron ore.
