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. 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.

21x27 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 21x27 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

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

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

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.

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.

Sustainable Forests - A Precious Natural Resource

The air that we breathe depends upon our healthy forests the world over. For this reason, we only use lumber from the sustainable forests of the Pacific Northwest, so we can guarantee that our nation's precious natural timber resources are available for future generations.

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.

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

With the brush, we merely tint, while the imagination alone produces color. ♦ Robert Delaunay

Delving into the mind of Robert Delaunay, one discovers a profound belief in the power of the imagination over mere tools of the trade. Delaunay, a key figure in early 20th-century art, often emphasized the transcendental aspect of art-making. For him, the physical act of painting - the strokes, the blends, the techniques - were just a gateway. The real essence, the true color, sprung from a deeper well within: the artist's imagination.

Artists constantly find themselves at this intersection of technique and inspiration. While tools and skills are crucial, it's the imagination that breathes life into our creations. It serves as a reminder that our true palette lies not in the paints we use, but in the depths of our thoughts, feelings, and experiences. So, in our creative endeavors, we should remember to let our imaginations roam free, allowing them to infuse our work with colors only we can produce.

Creativity is a dance between inspiration and innovation. Our own self portrait creation of Robert Delaunay twirls alongside these profound words, hoping to set the stage for your next artistic performance. Now go do your dance on the canvas!

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.
