15x21 Vincent Pro Pau Canvas 7/8 Inch Deep #VP-1521

True 7:5 Photography Proportion - 15x21 Size

Another widely used proportion in photography is the 7:5 aspect ratio, but is relatively uncommon in art, save for the 5x7 size. It is commonly accepted as a pleasing proportion. Some artists choose this proportion to add visual interest by breaking away from more traditional shaped canvas sizes. There are only a handful of standard canvas sizes in this ratio, but there are a whole collection of (what we call) Lost Sizes in this aspect ratio, which are often unknown sizes that add intrigue to the final composition.

Titanium Dioxide (TiO₂) Primer Pigment

This primer contains premium-grade Titanium Dioxide (TiO₂) white pigment, renowned for its exceptional performance in acrylic priming. Its standout feature is its enduring whiteness, coupled with remarkable flexibility that persists over time. In contrast to other pigments such as zinc dioxide, Titanium Dioxide maintains its resilience, preventing brittleness as it ages. This quality ensures that artworks retain their integrity and will stand the test of time.

Artfix Pau™ Portrait Smooth Belgian Linen offers a luxurious surface, ideal for highly detailed work. Preferred by portrait artists because it is so smooth for linen. Due to the nature of how flax plants are turned into linen textiles, there may be variations in yarn thickness thereby creating fabric that is individual in nature and has character. There can be infrequent naturally occurring nubs in the linen which may yield small slight bumps where the linen is a little thicker than the rest of the strand. This is normal and part of what gives linen its character.

Vincent™ Pro 7/8" Deep Bar • 5/16" Canvas Clearance

5/16" Canvas Clearance is the space between the Bar and the canvas. Generally speaking, more clearance reduces the risk of the canvas touching the wood and creating unsightly lines during painting. Our design provides the optimal clearance so as not to impact your painting, but still leaving enough wood to the maximize strength of the Stretched Canvas Frame.

• Stretcher Bar Profile produces a 7/8" deep stretched canvas
• 1.5" wide Stretcher Bar
• Frames with a dimension of 16" and up have a groove machined in the center inside perimeter to which cross braces attach
• Solid Ponderosa Pine or Fir from the Pacific Northwest

Solid Wood is Archival - Finger Jointed Wood is Not

We only use Solid Wood to build our Stretcher Bars because a solid piece of wood will last indefinitely. When we speak of archival value, it's not just the paint you use and the quality of your canvas and ground, even the wood choices manufacturers make are part of the archival process.

The principal reason manufactures use finger jointed wood is reduce cost, not increase archival value. Wood constantly grows and shrinks when the environment becomes hotter, or colder, or more humid, or more dry. Because finger jointed wood is made-up of multiple and varied pieces of wood, with varying grain patterns and densities, they each absorb and shed moisture at varying rates, which works on the glue joints that hold them together, causing the wood to bow and the joints to eventually fail, and certainly not consistent with increasing the archival value of your artwork frame support.

As a manufacturer, we do our part to conserve as much wood as possible, and still provide a quality made product that will out-perform any other in the marketplace.

15x21 Vincent ProE Extra Heavy Frame Provides Maximum Support!

• Drawing depicts the exact frame construction, not the proportion
• Precision machined medium duty keyable tongue-and-groove Stretcher Bars
• A 1/2" thick super strong keyable brace (3.25" wide) provides maximum support for this 21 long frame - Brace may be removed in reinserted at any time
• An exclusive slot is milled on the inside perimeter of the 21 Stretcher Bars to which the Brace and the expansion wedges attach
• Patented keyable cross braces allow the frame to be tensioned in the middle of the canvas, where the tension needed the most
• To increase canvas tension: 1) remove any staples in the corners and those that retain the brace keys in the middle, 2) tap all of the expansion keys further into their respective slots, 3) tighten and re-staple the canvas in the corners

Canvas Tension is in Your Control

In dry climates or air conditioned environments, the lack of moisture in the air causes wood frames to shrink and the canvas fibers to narrow and elongate making the canvas more slack and resulting in a loss of canvas tension. In some instances, the canvas could have waves on the surface resulting in an unsightly viewing experience.

Our Vincent™ Pro professional frames provide the functionality for you to slightly expand the size of the frame in the corners and the middle of the canvas, thereby increasing canvas tension all across the surface. The difference between a loose canvas and a tight canvas is just 1/8", so a small adjustment using our corner and brace keys makes an important difference in canvas tension.

• Helps to prevent waves that occur in a loose canvas
• Increase canvas tension by tapping-in the corner and brace keys
• True professional class canvases make it possible for you to adjust the canvas tension

Cross Braces Make it Tighter

A tightly stretched canvas on an un-braced frame overpowers the Stretcher Bars causing them to bow inward and thereby lose tension. Sometimes that bow can expose a space in picture frames.

When a canvas is stretched on a properly supported frame, the cross-braces prevent the Bars from bowing thereby achieving maximum canvas tension. To increase the canvas tension even more, simply tap the corner and brace keys further in their slots. Properly supported frames provide you with the control over the canvas tension of your canvas and painting.

Patience serves as a protection against wrongs as clothes do against cold. ♦ Leonardo da Vinci

Leonardo da Vinci, one of the most diversely talented individuals in history, wasn't just a master of art, but also an observer of life and human nature. He lived in a time of political upheavals, power struggles, and intellectual revolutions. Yet, in the midst of such a turbulent age, he distinguished himself not just by his prodigious output, but by the depth of his thought.

For many artists, the path of creation is fraught with obstacles: criticism, doubt, and myriad external challenges. Just as the cold can be biting and relentless, so too can the world seem in its assessments and misunderstandings. But da Vinci offers us a shield: patience. With patience, we can endure, outlast, and ultimately prevail. Just as clothes protect us from the harshest elements, patience armors us against the precipitate judgments and transient opinions of others. Embracing this virtue, artists allow their work to mature, to evolve, and to reach its full potential, irrespective of immediate reactions.
