'''જસત''' કે '''સ્પેલ્ટર''' ( જેનો અર્થ જસત ની મિશ્ર ધાતુ પણ હોય છે), એ એક રાસાયનીક ધાતુ મૂળ તત્વ છે.આની રાસયણી ક સંજ્ઞા '''Zn''' છે અને [[અણુ ક્ર્માંક]] 30 છે. આવર્તન કોઠાના ૧૨ના જૂથનું આ પ્રથમ તત્વ છે. જસત અમુક હદે રાસાયણીક દ્રષ્ટિએ મેગ્નેશિયમ ની સમાન છે કેમકે તેમનો બંધનાક +૨ છે. Zinc is, in some respects, chemically similar to [[magnesium]], because its [[ion]] is of similar size and its only common [[oxidation state]] is +2. Zinc is the 24th most abundant element in the Earth's crust and has five stable [[isotope]]s. The most exploited zinc [[ore]] is [[sphalerite]], a [[zinc sulfide]]. The largest exploitable deposits are found in Australia, Asia, and the United States. Zinc production includes [[froth flotation]] of the ore, [[Roasting (metallurgy)|roasting]], and final [[extractive metallurgy|extraction]] using electricity ([[electrowinning]]).
 
[[Brass]], which is an [[alloy]] of copper and zinc, has been used since at least the 10th century BC. Impure zinc metal was not produced in large scale until the 13th century in India, while the metal was unknown to Europe until the end of the 16th century. [[alchemy|Alchemists]] burned zinc in air to form what they called "[[philosopher's wool]]" or "white snow".
