Glass/quartz composite surface

A glass/quartz composite structure comprising:

• aggregate in an amount greater than any other single material by weight of the composite structure, the aggregate comprising amorphous silica;
• quartz powder in an amount 5-20% by weight of the composite structure;
• and
• a binding resin,
• wherein the glass/quartz composite structure is devoid of crystalline silica.

A glass/quartz composite structure comprising:

• aggregate in an amount greater than any other single material by weight of the composite structure, the aggregate comprising amorphous silica;
• alumina in an amount 5-20% by weight of the composite structure;
• and
• a binding resin,
• wherein the glass/quartz composite structure is devoid of crystalline silica.

A method of manufacturing a glass/quartz composite slab, the method comprising:

• preparing a mixture of aggregate, quartz powder, and a binding resin, the aggregate being in an amount greater than any other single material by weight of the composite slab and comprising glass grit, nano-glass crystals, and/or amorphous silica;
• pouring the mixture in a mold;
• and
• compacting the mixture in the mold.
