Methods of forming a glass-ceramic article, the method are provided. Embodiments of the method may include initially nucleating a precursor glass composition at a first nucleation temperature and maintaining the first nucleation temperature for a pre-nucleating time period to produce a pre-nucleated crystallizable glass composition, wherein the pre-nucleated crystallizable glass composition comprises 5 wt % to 20 wt % crystalline phase ASTM C1365-18, forming the pre-nucleated crystallizable glass composition into an initial 3D shape; further nucleating the initial 3D shape for a nucleating time period to a second nucleation temperature to produce a nucleated crystallizable glass composition; and ceramming the nucleated crystallizable glass composition to a crystallization temperature and maintaining the ceramming temperature for a crystallization time period to produce the glass-ceramic article. The glass-ceramic article may have a final 3D shape is within 0.1 mm of the original design specifications.

A bulk material handling method includes conveying bulk material directly from a mobile bulk material container into a stationary bulk material container at a glass manufacturing facility. The conveying of the bulk material is performed via dense-phase pneumatic conveying and/or after non-human verification that the type of bulk material contained in the mobile bulk material container is the same type intended to be stored in the stationary bulk material container.

A glass fiber and method for producing the same are provided. The method includes a covering process, a sintering process, a mixing process, and drawing process. The covering process is implemented by covering a tungsten compound onto a plurality of surfaces of a plurality of inorganic particles to form a plurality of modified inorganic particles. The sintering process is implemented by sintering the modified inorganic particles in a nitrogen atmosphere having a temperature of between 400 C. and 1,000 C. The mixing process is implemented by mixing the modified inorganic particles into a glass raw material that is in a molten state. The drawing process is implemented by drawing the glass raw material mixed with the modified inorganic particles to form a plurality of glass fibers.
