A method of producing a glass briquette in which reclaimed glass fines are mixed with a binder material to create a mixture. The mixture is subsequently compressed in a chamber to form a briquette having the shape of the interior of the chamber. The reclaimed glass includes glass fines of a size of smaller than 10 mm. The method is performed without melting the glass fines such that the resulting briquette contains the discrete glass fines held in the binder and may be used as a furnace ingredient for later glass product production. The glass briquette may contain other batch ingredients required in the production of glass.

Provided is a hydrophobic silica aerogel blanket comprising holes, so that the diffusion of a surface modifier is facilitated in a blanket during a surface modification process to improve the efficiency of surface modification. Accordingly, the hydrophobic silica aerogel has not only excellent physical properties such as specific surface area and thermal conductivity, but also a controlled degree of hydrophobicity, and thus, can have high hydrophobicity.
