Abstract
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 ().
