{"title":"Sietto Geometric Collection","description":"\u003ch2\u003eSietto Geometric Collection cabinet hardware\u003c\/h2\u003e\u003cp\u003eThe Sietto Geometric Collection is a hand-made glass knob line that sets a round glass dot or disc onto a square or round glass base, a layered two-shape composition. Geometric is a knob-only art-glass family built on contrast of form, where the pairing itself is the design.\u003c\/p\u003e\u003ch3\u003eWhat identifies the Geometric look\u003c\/h3\u003e\u003cp\u003eThe signature is the shape-on-shape construction: a small round glass element fused onto a base that is either round or square, so each knob reads as a deliberate geometric pairing rather than a single blob. Three glass colors carry the line, an iridescent black, a slate grey, and a white, the iridescent option shifting tone with the light across the day. Metal bases come in Polished Chrome, Satin Brass, and Satin Nickel. Because the glass is hand-fused, placement and color vary slightly between pieces. The defining trait is that round-on-square or round-on-round layered glass geometry, a quiet graphic mark rather than a sculptural object.\u003c\/p\u003e\u003ch3\u003eBuying considerations\u003c\/h3\u003e\u003cp\u003eGeometric suits modern, artisan, and transitional kitchens, baths, and display cabinetry where a knob should be a small graphic accent. Choose the square base for crisper, contemporary doors and the round base for softer schemes, keeping one color across the run. The iridescent black is the most active in changing light; white and slate grey stay quieter. Match the metal base to your fixed metals. Since the line is knobs only, pair a coordinating pull elsewhere for wide drawers, and keep glass on lower-traffic doors than a wet sink base where it is handled with damp hands constantly.\u003c\/p\u003e\u003ch3\u003eRelated Sietto collections\u003c\/h3\u003e\u003cp\u003eThis line sits within the broader Sietto catalog; browse the full \u003ca href=\"\/collections\/brand-sietto\"\u003eSietto brand page\u003c\/a\u003e for other glass families.\u003c\/p\u003e","products":[{"product_id":"sietto-k-1300-geometric-geomtric-square-white-on-square-knob-k-1300","title":"Geometric Geomtric Square White on Square Knob K-1300","description":"\u003cp\u003eBring a crisp, modern edge to your cabinetry with the Sietto Geometric Square White on Square Knob K-1300—an artful shape-on-shape statement for everyday spaces.\u003c\/p\u003e\u003cp\u003eThe Sietto Geometric Square White on Square Knob K-1300 turns a simple touch into a designed moment.
