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.

21x70 Frame Kit B2 Super Heavy Frame Offers the Ultimate Canvas Support!

• Drawing depicts the exact frame construction, not the proportion
• Precision Machined keyable Super Strong Stretcher Bars (1.5" deep by 2-1/4" wide) allow you to increase the canvas tension
• Two Super Strong Keyable Braces and a Cross Brace Included (3/4" x 3.25")
• The Bars have a clever utility groove on the inside perimeter of the frame to attach the cross braces
• Unique Keyable Cross Braces allow you to tension the canvas in the middle, where it's needed the most
• Cross braces are glued and stapled at the 'cross' for maximum support and rigidity
• Both corner keys and brace keys are pre-installed

Elite™ Professional 1.5" Deep B2 Bar • 1/2" Canvas Clearance

A Canvas Clearance of 1/2" 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 Stretcher Bar.

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 we stretch a canvas 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.

What is Sustainable Forestry?

To a forester, the term "sustainable" could mean exercising industry adopted forestry practices to maintain a forest indefinitely. To a logger, the process of proper care for the trees remaining after a harvest. To a landowner, their interest may lie in keeping their forest in the family. And to those of involved in the process of making and using wood-based art supplies, it can mean promoting and supporting an industry dedicated to the preservation of our precious natural resource. We can all do our part to care for our national forests.

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 Elite™ 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

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.

Our quest at Masterpiece® is clear: deliver unmatched excellence. This dedication has positioned us as the nation's beacon of quality in the world of professional fine-art canvases. Delve into our curated selection of surfaces and roll sizes, each promising perfection for your artistic endeavors.

Water is the driving force of all nature. ♦ Leonardo da Vinci

Leonardo da Vinci, a polymath whose influence spanned art, science, and engineering, often sought inspiration from the natural world. Nestled in the heart of Renaissance Italy, he was surrounded by a landscape marked by its undulating hills, lush vineyards, and flowing rivers. This direct communion with nature fueled his boundless curiosity, allowing him to observe and dissect the world in a manner that was groundbreaking for his time.

For many artists, the elements of nature have always served as muses. Water, in particular, has this unique ability to mirror our emotions Ñ its calm surfaces reflect serenity, while its tempestuous waves echo turmoil. As we craft, mold, and shape, water's versatility serves as a profound metaphor for adaptability and change. We, too, must be fluid, adapting our techniques and perspectives to the evolving world and the ever-shifting emotions within us.

Leonardo's statement is more than just an observation of the physical world; it's a philosophical reflection on the essence of life and creativity. Every brush stroke, every line drawn, every sculpture molded carries with it the essence of nature's driving force. It is a nudge, urging us to delve deep, to be observant, and to let the flow of life and creativity guide our hands in our artistic pursuits.
