8x18 Vincent Pro Sierra Canvas 7/8 Inch Deep #VE-0818

True Dynamic Root-5 Proportion - 8x18 Size

This 8x18 is one of our Dynamic Root-5 Rectangle Root-5 Rectangle series.

The Dynamic Root-5 rectangle is an inspiring proportion based on organizing your spatial composition with endless symmetrical divisions. The premise in Jay Hambridge's 1926 book is that the Dynamic Symmetry of individual elements are informed by their relationship to the entire composition. This very special proportion is guided by the square roots of integers and has a storied and historical basis in art.

It involves the use of geometric shapes and patterns in the proportion of the square root of 5 to 1 to create balance and harmony in a composition. This can be achieved by dividing a composition into a grid of squares or rectangles, and then placing elements within the grid in a way that follows the principles of dynamic symmetry. Dynamic symmetry is often used to create a sense of order and structure in a composition, and can be particularly useful for creating compositions that are harmonious and pleasing to the eye.

Vegan Ground:

There are no animal products that make-up the sizing and the primer for this fine canvas. Historically, traditional canvas grounds have included egg tempura, pigments with cow urine, and of course, rabbit skin glue. In today's rapidly advancing world, there are many more choices available for artists who prefer non-animal based products that perform far better than their animal-based predecessors.

Titanium Dioxide (TiO₂) Primer Pigment

Our primer is made with the highest-quality Titanium Dioxide white pigment, which is an excellent pigment for acrylic primed grounds, providing superior whiteness and maintaining excellent flexibility over time.

8x18 Vincent Pro Keyable Braced Frame

• Drawing depicts the exact frame construction, not the proportion
• Precision machined medium duty keyable tongue-and-groove Stretcher Bars
• A 1/2" thick keyable brace (1.5" wide) provides sturdy support for this 8x18 size frame - Brace may be removed in reinserted at any time
• An exclusive slot is milled on the inside perimeter of the 18 Stretcher Bars to which the Brace and the expansion wedges attach
• Patented keyable brace allows 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

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

Finger Jointed Wood is not meant for Stretcher Bars

Solid wood makes the most dependable Stretcher Bar, because one homogeneous wood member is going to behave similarly across the entire length of the Bar. Whereas, with finger-jointed wood is made-up of multiple pieces of wood, sometimes on the actual joint itself, presenting multiple points of failure which no one can control.

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 add or reduce value to your final painting. The fact is, you don't want problems, and finger joints only increase that risk of the wood falling apart in the future.

The glue used to bind finger joints is a water based adhesive and when that wood is exposed to high humidity environments, particularly with exterior walls, the glue joints can give-up. As a manufacturer, Masterpiece® does its part to conserve as much wood as possible, and still provide a quality product that will out-perform any other in the marketplace.

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.

Sustainably Managed Forests Inhale and Exhale

The world's forests are essential to human survival. Forests inhale carbon dioxide for the earth, and exhale oxygen essential for life. When we speak of the sustainable forest strategy of ensuring that more timber will exist in the same forest land than exists today, this is the only viable plan for the future of humanity. For this reason, we use only lumber from the sustainable forests of Oregon, Washington, and California, where thereÕs more standing timber today than last century!

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" of an inch, 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

MuseumWrap™ Stretching Technique

With more than a half a century of American engineering, Masterpiece® designs and builds its own proprietary stretching equipment that enables us to produce the finest and most tightly-stretched canvas on the market.

• Drum-tight stretch!
• Up to 50% tighter than other methods
• Balanced tension across the surface
• Uncut folded corners make it possible to remove and re-stretch canvas on the same size frame
• Usually the corner folds are on the long sides

A canvas is one of the very few products you can buy, and with your precious time, talent, and materials transform it into a work of art that could one day be worth a fortune. Don't skimp on your material choices! Your legacy and your own brand will be judged by how well your artwork stands the test of time.

I've been 40 years discovering that the queen of all colors was black. ♦ Pierre-Auguste Renoir

For many artists, like Pierre-Auguste Renoir, the realization of the importance of certain elements in their work comes only after years of exploration and experimentation. Renoir, a principal innovator of Impressionism, initially used vibrant hues to capture the luminosity of life. Yet, his declaration about the color black reveals a profound appreciation for the depth, contrast, and richness it brought to his masterpieces.

Black, often associated with absence or void, has a unique power in adding depth and dimension to a canvas. For artists, embracing the subtleties and strengths of each color is a part of our evolving understanding of our medium. Just as Renoir found beauty and power in the darkest of shades, we too can discover unexpected truths and emotions in the overlooked or previously undervalued aspects of our craft.

Tight'n'Up™ Liquid Canvas Retensioner

While all of our Masterpiece® Pro canvases are stretched very tightly and our frames have a built-in method to increase tension, we have another method to add canvas tension. Tight'n'Up™ Liquid Canvas Retensioner (sold separately) can be sprayed on the back of a canvas to repair most canvas tension issues.

With Tight'n'Up™, you can add tension to just a small area, or a large area. Simply spray it lightly on the back and brush it into the canvas, and within seconds, your canvas becomes tighter and stays tighter. The more you use, the tighter it gets.
