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.

Muir™ Acrylic Primed Belgian Linen

• 100% Belgian Linen 5 oz; Primed Weight 12 oz per square yard
• Medium Weight, Open Weave, Textured Surface
• Double Sized and Double Primed with acid-free archival quality acrylic gesso
• Impenetrable ground prevents oil paint from leaching through and harming the canvas
• For acrylics, oils, alkyds, and water miscible oil paints
• Linen has natural oils that prevent disintegration over time

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. Unlike some other common pigments, such as zinc dioxide, TiO₂ doesn't become brittle as it ages, helping to ensure that your painting will stand the test of time.

13x21 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 13x21 size 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 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

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.

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

To understand our era, one must appreciate the grandeur of abstraction. ♦ Robert Delaunay

Robert Delaunay, a stalwart of the Orphism art movement, was profoundly influenced by the potent force of abstraction. This French artist observed the shift from representational art to the abstract, recognizing its impact not just on the art world, but on the zeitgeist of the times. The 20th century witnessed technological advancements, societal upheavals, and rapid changes. Amidst this transformation, abstraction emerged as a form that transcended boundaries, offering artists a new vocabulary to express their perceptions.

Embracing abstraction means challenging traditional norms, pushing boundaries, and ushering in fresh perspectives. It becomes a mirror reflecting the complexity and dynamism of our age. The shapes, forms, and colors, devoid of literal representation, allow us to delve into deeper emotional and intellectual explorations. This liberation in art paves the way for us to approach our work with a renewed spirit, understanding that art is ever-evolving, just like the world around us.

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.
