"Crystallized glass" is obtained by re-heating glass and keeping it at a temperature above the liquid phase for an extended period, allowing its main components to precipitate as crystals. In most cases, it becomes opaque. By precipitating crystals, chemical durability and thermal properties can be enhanced. Many products take advantage of this feature, with one application being artificial marble. [Features] - Re-heating treatment of glass - Hardening and opacification - Improved chemical durability and thermal properties - Applicable to artificial marble and other products For more details, please refer to the catalog or feel free to contact us.

The "Glass Terminology Collection" is a catalog that compiles terms related to glass from Akagawa Hard Glass Co., Ltd., which provides better glass products. It lists terms related to the glass manufacturing process and properties in alphabetical order. We hope it will be useful to everyone, so please make use of it. [Terms Included] ■ A Section - Abbe Number - Arrhenius Equation ■ K Section - Numerical Aperture - Easy-to-Cut Glass, etc. *For more details, please refer to the catalog or feel free to contact us.

At our company, we consistently carry out the processes of raw material blending, melting, and molding, and we would like to share some voices from the artisans (technicians) who excel in these areas. - Teamwork in Hand-Blown Glass (Excerpt) Glass will never be in exactly the same state as it was yesterday due to the temperature of the furnace and the way the molten glass is rolled. I have been in this field for 37 years, and there is never a point where I can say, "This is good enough." Creating glass is a lifelong learning experience. - Individual Skill Shines in Blown Glass (Excerpt) Hot glass is gooey and softer than taffy. I always think how amazing the skilled technique is to wrap that glass material around a rod and transform it into a glass rod of uniform thickness. Only the meticulously selected pieces, with no room for even a slight deviation, become products. You can view the full text on our company website.

Our company is a glass factory that consistently performs raw material formulation, melting, and molding. We process molten glass into granules, valves, pipes, rods, and perform press molding, among other forms. Among these, the production of glass tubes with customizable inner and outer diameters is our strength. One person spins a rod with molten glass while stretching the glass into beads, while another checks the dimensions with a fan. Additionally, we accommodate small lot production that cannot be done by machines, custom manufacturing for prototype requests, and high-temperature glass production around 1600°C. 【Our Strengths】 ■ Production of glass tubes with customizable inner and outer diameters ■ Small lot production that cannot be done by machines ■ Custom manufacturing for prototype requests ■ High-temperature glass production around 1600°C *For more details, please refer to the PDF document or feel free to contact us.

Our company possesses a variety of equipment. For example, the "single furnace" allows for the production of tube glass, blown glass, and crushed glass by heating each cat-shaped crucible individually to perform glass melting. The "redraw device" heats the parent material of tube glass to temperatures between 600°C and 900°C, enabling the production of thin tube glass. In addition, we also have a "V-type mixer" and various measuring devices. 【Equipment Owned (Excerpt)】 ■ Single Furnace ■ Various Test Furnaces ■ Redraw Device ■ Glass Cutting Machine / Glass Polishing Machine ■ V-Type Mixer *For more details, please refer to the PDF document or feel free to contact us.
