Designed for Gathering

Classical Proportion, Refined for a Modern Patio

The stepped body creates shadow lines that change as the sun moves, while metal bands trace the profile with a restrained contrast.

At 14 inches high, Cronus keeps the flame close to seated eye level and preserves views across the patio despite its substantial four-foot footprint.

  • Made to order: approximately 6–8 weeks before transit

Built for Outdoor Projects

Concrete, Metal, and Brass in One Composed System

Cronus is hand-cast from glass fiber reinforced concrete in Denver, Colorado, then detailed with slim metal inlays around its stepped profile. Natural changes in finish and texture make each vessel individual.

The 180,000 BTU Warming Trends Crossfire brass burner provides adjustable flame control through the included key valve after professional installation.

Stepped Profile

Tiered concrete geometry creates depth and changing shadow lines.

Metal Inlays

Slim bands provide a tailored architectural accent around the vessel.

Complete Package

Burner, plate, valve, flex hose, lava rock, cover, and leveling feet are included.

Concrete Finishes

Four Tones for the Surrounding Architecture

Finish samples and screens can display color differently. Natural variation in hand-finished concrete is expected.

Birch

A warm light neutral for pale stone, limestone, and natural wood palettes.

Smoke

A balanced mid-grey suited to contemporary hardscapes.

Carbon

A deeper charcoal that adds visual weight and contrast around the flame.

Onyx

A near-black option for high-contrast modern installations.

Finish disclosure: Color, movement, texture, and small surface characteristics will vary from online images and physical samples. Small hairline lines may form during curing as moisture leaves the concrete; the manufacturer states these should not affect long-term stability and are not considered manufacturing damage.

Common Questions

Cronus Buying Guide

What distinguishes Cronus from the other square models?
Cronus adds a stepped profile and slim metal band inlays to the 48-inch square. Notus is a simpler low square available in two sizes, while Chaos uses a more monolithic sculptural form.
How is the flame adjusted?
The included key valve controls gas flow to the Crossfire burner, allowing the flame to be raised or lowered after the system is properly installed.
Can Cronus be ordered for propane?
The variants currently selectable on this page are configured for natural gas. Contact Smokeforges before ordering so a current liquid propane configuration, price, and production estimate can be confirmed.
What clearances should be planned?
The published burner diagram calls for 120 inches of vertical clearance and 36 inches of horizontal clearance from the burner to combustible materials, plus 18 square inches of ventilation on each of two opposing sides. A qualified installer should confirm the project.
What warranty applies?
Studio Nisho currently lists a one-year manufacturer warranty against manufacturing defects on the vessel and a lifetime manufacturer warranty on the brass burner, subject to the manufacturer's current written terms.
