The Journey of a Million Years

Your countertop started as magma cooling deep inside the earth 300 million years ago. But how did it get from a mountain in India to your kitchen? Here is the industrial journey of a Ruvello slab.

Step 1: The Quarry (Extraction)

We locate a deposit of Black Galaxy. We don't use dynamite (which shatters the stone). We use diamond-wire saws and expansive mortar to gently push a "bench" (massive wall of stone) away from the mountain. This is cut into blocks weighing 20-30 tons.

Step 2: The Factory (Gangsaw Cutting)

The block arrives at our factory. It is loaded onto a "Gangsaw"—a massive machine with 80+ steel blades moving back and forth. We feed water and steel grit (slurry) into the cut. It takes 2-3 days to slice one block into 2cm or 3cm raw slabs. This creates the "Sawn" finish.

Step 3: Reinforcement (Epoxy Resin)

Most natural stones have micro-fissures. We place the raw slabs in a vacuum chamber and pour high-flowing epoxy resin over them. The vacuum sucks the resin deep into the stone, filling every tiny void. This strengthens the slab by 40% and allows for a better polish.

Step 4: Polishing (The Shine)

The slabs run through a 20-head automated polishing line. The heads start with coarse diamond grit (50 grit) and move up progressively to 3000 grit and finally a buffing pad. This closes the pores and creates the mirror finish you see on Absolute Black.

Step 5: Inspection & Bundling

An inspector checks every inch. Scratches? Rejected. Color blotch? Rejected. The good slabs are "bundled" together (usually 6-8 slabs per bundle) so they travel together. This ensures that if you buy 3 slabs for a kitchen, they all come from the same block and match perfectly.
