Muir™ Acrylic Primed Belgian Linen

Characteristic linen type surface texture. It has a bright white tone.

• 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.

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

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.

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

No Finger Joints!

Solid Wood is far superior to finger jointed wood, which is many small pieces glued together, each with varying grain densities that absorb and shed moisture at varying rates, expanding and contracting non-uniformly as environmental conditions change, and causing the wood to bow and the finger joints to eventually fail.

A single homogeneous kiln-dried solid wood Stretcher Bar outperforms and outlasts a finger jointed Bar whose sole purpose is to save the manufacturer cost, not contribute to the archival value of artwork intended to last a millennium. 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.

21x28 Vincent Pro Keyable Cross Braced Frame

• Photo displays the exact frame construction, not the proportion
• Precision machined medium duty keyable tongue-and-groove Stretcher Bars
• Two 1/2" thick keyable cross braces (1.5" wide) provide excellent frame support for this 21x28 size - Cross braces may be removed and reinserted at any time
• An exclusive slot is milled on the inside perimeter of all of the Stretcher Bars to which the Braces 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
• Cross braces firmly attached with hardware at the intersection point for maximum support and rigidity

What's so important about keyable canvas frames?

In dry and air conditioned environments, wood can shrink and canvas fibers elongate, thereby making the canvas looser to the point where you might see waves in the canvas. Keyability is an important feature that professionals cherish because it makes it possible to increase canvas tension without having to re-stretch it. There is a risk to re-stretching a canvas as it could apply undue stress on the paint across the surface which could accelerate cracking of the paint, particularly with oil paintings.

With Masterpiece's patented framing systems, you can tap the keys into the corners as well as the ends of the braces, which expands the canvas more equally across the entire surface. The difference between a loose or tight canvas is just 1/8", so even small adjustments with corner and brace keys can improve a stretched canvas.

To increase canvas tension:

1. Remove any staples in the corners above and below the canvas
2. Remove any staples that restrict the keys in the corners and braces
3. Tap all the expansion keys further into their respective slots until desired tension has been achieved
4. Using canvas pliers, tighten the canvas in the corners and staple
5. Canvas tension will be restored

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.

Biodiversity in our Forests is the Key to Life as we know it

By using lumber from sustainably managed forests in our products, we can ensure that the forests will continue to thrive and provide valuable resources for years to come. Sustainable forestry practices help to maintain the health and biodiversity of the forest, which benefits not only the environment, but also the local communities and businesses that rely on the forest for their livelihoods.

Specially Dried and Heat Treated Lumber

We source our wood from a select group of top-tier environmentally conscious lumber mills in the Pacific Northwest. These mills specially dry and heat-treat the lumber to our specifications, resulting in about half the moisture content compared to wood from typical home improvement centers or lumber yards. This process makes the wood stronger, reducing the likelihood of cracking, splitting, or warping. While the wood we use comes at a higher cost, it ensures a more dimensionally stable end product. This stability is crucial for crafting fine professional canvases that support your invaluable art over time.

MuseumWrap™ Stretching Technique

With more than 60 years 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

Since 1965, our passion for perfection has driven us at Masterpiece® to construct professional quality canvases that artists around the nation desire. Your art is better and more valuable when the materials you use are complementary to the blood, sweat, and passion you will paint on top.

Carving is easy, you just go down to the skin and stop. ♦ Michelangelo

Michelangelo, a master sculptor whose monumental works have become emblematic of the Renaissance period, often spoke with a humble irony. His comment on carving simplifies the meticulous and labor-intensive process of sculpture, making it sound almost effortless. Yet behind this seemingly casual remark lies a profound understanding of his medium. Knowing when to stop, understanding the material's limits, and visualizing the final piece even before the first chisel strike are attributes that defined Michelangelo's genius.

Understanding the boundaries of our mediums, whether it be canvas, stone, or something else entirely, is paramount. We intuitively learn when to add another brushstroke, when to mold or reshape, and crucially, when to step back. It's not just about the technical act of creating, but the discernment and judgment we exercise throughout. Like Michelangelo, we too find our art not just in the act of creation, but also in the myriad decisions that guide us to the final masterpiece.
