The invention provides a crystal glass digestion method and a method for measuring lead content of crystal glass. The method comprises the following steps: adding crystal glass ground into powder into a polytetrafluoroethylene digestion tank, adding hydrofluoric acid, nitric acid and hydrogen peroxide, wherein the volume ratio of the hydrofluoric acid to nitric acid to hydrogen peroxide is (3-5):(1.5-2.5):1, sealing the polytetrafluoroethylene digestion tank, and performing microwave digestion on the polytetrafluoroethylene digestion tank in a microwave digester; cooling the mixture obtained in the reaction to normal temperature, transferring the mixture into a platinum crucible, adding nitric acid and perchloric acid, wherein a volume ratio of the nitric acid to perchloric acid is 1:(1.5-2.5), heating the platinum crucible, and performing secondary digestion on the crystal glass. After digestion, the lead content can be measured by adopting methods such as flame atomic absorption spectrophotometry. The method has the beneficial effects that 1, the crystal glass digestion process is low in time consumption; 2, the digestion operation is complete, and the detection accuracy is high; and 3, the use amount of the sample is small, and environmental pollution is avoided.
