Abstract
A method of manufacturing glass spacers is provided which can enhance the degree of similarity in cross section between the mother glass and the drawn glass when manufacturing glass spacers by hot drawing the mother glass. A mother glass having a similar cross section to a desired cross section of the glass spacers is prepared. The mother glass is drawn while it is heated to a viscosity of 105 to 109 poise.
Claims7
A method of manufacturing glass spacers, comprising the steps of:
- preparing a mother glass having a similar cross section to a desired cross section of the glass spacers;
- drawing the mother glass while heating the same to a viscosity of 108 to 109 poise;
- and
- cutting the drawn glass into a plurality of glass spacers;
- wherein an aspect ratio proportion is calculated as
- R=(B/A)×100%
- where R is the aspect ratio proportion, B is an aspect ratio of the glass spacers, and A is an aspect ratio of the mother glass;
- and
- wherein the aspect ratio proportion is within a range of 92.2% to 100.3%.
