Provided is a glass production method with which oxidation can be easily prevented and productivity can be increased. The glass production method includes a step of allowing a melt (), which is obtained by melting a glass raw material, to flow into a mold () and a step of cooling the melt () to yield a glass (). A partition member () is disposed in the mold (), forming an inflow portion () surrounded by the mold () and the partition member (). In the step of allowing the melt () to flow into the mold (), the melt () flows into the inflow portion () while the mold () is moved relative to the partition member () to increase the capacity of the inflow portion ().

Glass production method

Provided is a glass production method with which oxidation can be suppressed and productivity can be increased. A glass production method according to the present invention includes the steps of: turning a raw materialplaced in a containerinto a melt; homogenizing the melt; removing a gas from the melt, wherein at least one of the step of turning the raw materialinto the meltand the step of homogenizing the meltis performed in an atmosphere of an inert gas or a reducing gas, and in the step of the removing the gas from the melt, the inert gas or the reducing gas is removed by setting the temperature of the meltto be lower than the temperature in the step of homogenizing the melt
