Claim 15:
16. The glass furnace as claimed in claim 1,
the additive-containing product being obtained by a method comprising the following steps in succession:
A) preparing a feedstock comprising a particulate mixture and water,
B) shaping said feedstock in a manner such as to form a preform;

a precursor of said additive being applied to the surface of the preform, the content by weight of additive precursor being in the range 0.01% and 5% on the basis of the weight of the preform after depositing the additive precursor and/or,
the additive-containing product being obtained by a method comprising the following steps in succession:
A) preparing a feedstock comprising a particulate mixture and water;
B) shaping said feedstock in a manner such as to form a preform;
C) sintering said preform in a manner such as to obtain a sintered product,

a precursor of said additive being applied to the surface of the sintered product, the content by weight of additive precursor being in the range 0.01% to 5% on the basis of the weight of the sintered product after depositing the additive precursor.
