1. A low-temperature process for the fabrication of lightweight composite glass ceramic structures, comprising:

  • providing a plurality of glass ceramic components, said glass ceramic components each being polished to form at least one joining surface on each component, providing a silicate-containing joining liquid to at least one of the joining surfaces, bringing the joining surfaces of the plurality of glass components together to form a joint, allowing the joint to cure for a period of time of at least 20 hours at a temperature of at least 20 degrees C., whereby a cured joint is formed between said plurality of glass components, and dehydrating the cured joint gradually by raising the temperature slowly and maintaining an elevated temperature below the glass transition temperature of the glass ceramic for at least 20 hours.
