    Abstract: Embodiments of a method of forming a glass article are disclosed. The methods include supplying a glass ribbon in a first direction and redirecting the glass ribbon to a second direction different from the first direction without contacting the glass ribbon with a solid material. The glass ribbon may exhibit a viscosity of less than about 108 Poise and a thickness of about 1 mm or less. Embodiments of a glass or glass-ceramic forming apparatus are also disclosed. The apparatus may include a glass feed device for supplying a glass ribbon in a first direction and a redirection system disposed underneath the glass feed device for redirecting the glass ribbon to a second direction. In one or more embodiments, the redirection system comprising at least one gas bearing system for supplying a gas film to support the glass ribbon.
