Grapeva Forge

Grapeva Forge is a bench for one question: will this surface shed water, or soak and stain? 1. Set the panel. Pick the material you actually own — clear-coated steel, float glass, waxed cotton, light woven shell cloth, bare sawn timber, varnished timber, unglazed clay, glazed ceramic, anodised aluminium, nubuck leather. Each carries its real surface energy and its own texture. 2. Put a drop on it. Choose the liquid, the drop volume in microlitres, the surface temperature and the tilt of the panel. The stage draws the sessile drop in section at true scale, flattened exactly as far as its own weight flattens it, against a millimetre rule. 3. Read the verdict. Grapeva Forge computes the equilibrium contact angle from surface energy and texture, the shed class — beads, clings or soaks — the angle the panel must reach before the drop runs off, and the impact regime a raindrop hitting it at terminal speed ⚡ produces. 4. Generate a proofing run. From the panel and the finish, Grapeva Forge lays out the prep, the coats and the interval between them, the cure window, the week 🗓️-by-week decay of the angle, and the date the surface stops shedding. 5. Photograph the patch. The same spot before treatment and after it, each sitting under its computed profile at the same scale, so the real bead can be held against the modelled one. 6. Keep the record. Every run is filed with its measured angle, its shed class, its cure date and its re-do date. Ten panels, eight finishes, six liquids and six fault patterns are built in. Every number 🔢 on every screen is computed on the device 📱 from the values you set, and changes the moment you change them. Grapeva Forge works fully offline 📴.
