A method for producing a glass furnace, including a refractory portion, a waveguide with a measurement portion extending into the refractory portion and an interrogator connected to an input of the waveguide to inject an interrogation signal. The measurement portion incorporating a sensor to send a response signal to the interrogator in response to the injection. The interrogator analyzing the response signal and sending a message. Arranging, inside a mold, a temporary part configured to leave space for a compartment for the measurement portion. Preparing a starting feedstock and introducing the starting feedstock into the mold such that the part is embedded therein to obtain a preform. Hardening the preform to form the refractory portion. Removing the temporary part to make the compartment. Assembling the refractory portion with other constituent elements and introducing the measurement portion into the compartment and connecting the interrogator to the input of the waveguide.

There are provided a liquid vessel which is capable of being configured in a large size of prefabricated form, and a method for producing a glass product. A liquid vessel for holding a liquid, comprising at least a first member, a second member and a third member; and a first engageable portion and a second engageable portion being configured such that the first member and the second member are brought into contact with each other to be engaged, and a third engageable portion being configured such that the third member is brought into contact with the first member and the second member in a direction intersecting an engagement direction of the first member and the second member to be engaged with the first member and the second member.

A corner block for a glass furnace tank. The corner block has an outer surface including: upper and lower surfaces delimiting the length of the corner block, right and left surfaces to be in contact with corresponding surfaces of adjacent blocks, a hot face to be in contact with the environment inside the tank, and a cold face, opposite the hot face. A main portion of the corner block extends, over more than 80% of the length of the corner block, between two limiting upper and lower transverse planes. The hot face is edge-free. An edge is a line along which the hot face has a break in slope greater than 25°. The hot face has a profile that is convex in any transverse sectional plane in the main portion.

An industrial furnace for melting materials is provided. The industrial furnace includes metal components, a refractory shell, and a fill. The refractory shell is positioned to cover an inner surface of the metal components such that one or more pockets are defined between the metal components and the refractory shell. The refractory shell has an inner surface that substantially defines a melting bath in which the materials are deposited for melting. The fill is disposed in each of the pockets. 90% to 99.5% of the fill is composed of one or more magnesia materials selected from the group consisting of dead-burned magnesia and fused magnesia.

In embodiments, a melter for melting glass may include an inlet wall, an outlet wall opposite the inlet wall, and sidewalls extending from the inlet wall to the outlet wall. The inlet wall, outlet wall, and sidewalls define a glass melting space enclosed by a floor and a top. In embodiments, the inlet wall may comprise a glass contact wall comprising a glass contact surface facing the glass melting space. A superstructure of the inlet wall comprises a jack arch positioned over the glass contact wall and at least a portion of the glass melting space. A plane of an interior face of the jack arch and a plane of the glass contact surface are off-set in a horizontal direction. A vertical distance from the floor to an underside of the jack arch is less than a vertical distance from the floor to an underside of the top.

In manufacturing a glass article (GR) by causing a molten glass (GM) to flow through a transfer pipe (12) and to be transferred, the transfer pipe (12) includes: a pipe end portion (14) being an end portion in a pipe axis direction; a pipe-shaped portion (15); and a joining portion (16) configured to join the pipe end portion (14) and the pipe-shaped portion (15) to each other. The pipe end portion (14) includes a flange portion (17) and a curved portion (18) extending from an inner peripheral end (17a) of the flange portion (17) toward the pipe-shaped portion (15) side and being reduced in diameter toward the pipe-shaped portion (15) side. The pipe end portion (14) is made of a material having a smaller creep rupture strength and/or a larger creep strain rate than the pipe-shaped portion (15) at 1,500° C. and 1,000 hours.
