Types of Stretcher Bars

Stretcher bars play a major role in the appearance of a canvas artwork or Giclee printing. The quality of wood and the structure of the stretcher are the key to easy stretching which produces a better print quality and longer life for a canvas. It is also important that you choose the right stretcher for your canvas depending on the type of canvas you will use, the size of your artwork and weight and texture of the weave of the canvas. The following are the types of stretcher bars and their uses.

Medium/Standard Duty
Medium duty stretcher bars are the standard stretcher bars with raised and rounded edges which significantly reduce the friction of stretching. It provides a tighter and more even canvas face. It also reduces the stress placed on the canvas and the person doing the stretching, as pliers lever the canvas around the frame.

Light Duty
Light duty stretcher bars are great for those smaller paintings or giclee prints that will be framed or won’t benefit from a thicker bar. They have a beaded (rounded) edge that holds the canvas and flat part of the bar slightly apart. The rounded edge greatly relieves the stress on the canvas and person framing. A tighter, more uniform stretch is the result of this feature because the canvas flows around the smooth edge.

Medium/Heavy Duty- Goldilocks
Goldilocks medium or heavy duty stretcher bar is an expensive option because it is in demand for those who require a substantial side profile for their valuable art work. It adds to the intrinsic value of the art without having to spend more. This stretcher profile is frequently used for the stretching of giclee and other prints.

Heavy Duty-Midi
Heavy duty Midi bars offer you an exceptional quality at a very reasonable price. Like all other gallery wrap stretcher bars, their edges are created to impart a smoother stretching with less resistance. These light-weight bars are also perfect for reducing the overall weight of the frame. Straight-grained and lightweight these bars are perfect for also reducing the overall weight of the frame.

Super Heavy Duty
The super heavy duty gallery wrap stretcher bars are known for their impressive mass as well as strength. It is very useful when you have to stretch that large canvases and paintings. It is also ideal for smaller frame applications where very high tension is required. They are usually made with a brace at the back for added strength.

Types of Painting Easels: An Introduction

Dictionary.com defines easel as “a stand or frame for supporting or displaying at an angle an artist’s canvas.” Easels are usually made of wood, steel, or aluminum and are available in different designs. Here are the different types of easels in the market:

1. A-frame or Lyre easel. The A-frame easel has a tripod design, meaning, two legs in front and one in the back. It provides a strong base for your painting and it’s small size makes it easy to move and store in your studio. The legs are collapsible so you can just fold the legs and keep it in your storage when you’re done painting. If you have a small space, an A-frame easel is perfect since it will not crowd your studio. A-frame easels can hold small size canvases up to 75″ canvases.

2. H-frame easel. As the name suggests, an H-frame easel looks like the letter “H.” It has parallel vertical posts and a horizontal crossbar support. It gives sturdier support compared to A-frame easel but it’s quite bulky. An H-frame easel can hold bigger canvases, up to 84″-96″.

3. Single mast easel. The single mast easel is the simplest type of easel. It doesn’t offer the same support as the A-frame and H-frame easels but because of its affordability, many art students and beginners opt to use it. It occupies less space (great for small apartments and school studios), is collapsible, and easy to store.

4. Giant easel. The giant easel is made for artists doing large-scale paintings. It can handle canvases taller than 8 ft so naturally, this easel is stronger and sturdier. Due to its weight, transporting a giant easel is not easy. If you are consistently working on large-scale paintings, use a giant easel but make sure that you have a dedicated studio where you can use and store it.

5. Convertible easel. The convertible easel, also called hybrid easel, is the most versatile among all other easels. You can position your canvas horizontally or vertically, depending on the surface needed by the medium you’re using. This easel can accommodate the needs of painters using oil, acrylics, watercolor, and pastels. If you’re an artist who uses several media, the convertible easel is best for you.

6. Table top easel. The table top easel can be placed on a table and allows the artist to sit while painting. It is great for those who work on small-scale paintings and those who have limited space in their room or studio. It is portable and stores easily.

7. Plein air easel. The plein air easel is the easel that you can use outdoors. It has tripod legs and can have drawers and shelf to hold your painting supplies and materials. It can hold canvases up to 45″-78″ high.

8. Bench easel. The bench easel combines an easel and a bench. The design allows you to sit while painting. It is collapsible so you can bring it anywhere. It is great for plein air artists, art teachers, or for those giving demonstrations.

9. Display easel. The display easel is not for painting, just for displaying paintings only. It is made of lighter material so it cannot hold heavy artworks. Use the display easel when you are having an art show or any event where you need to showcase your work.

10. Children’s easel. The children’s easel is created for kids. It is adjustable and most designs have two sides, allowing a couple of children to work on their paintings. It offers built-in storage where children can keep their art supplies.

How to Use Gesso on a Canvas

Gesso? What is it?

Most beginners in painting may be unfamiliar with the word “gesso.” It’s a highfaluting term that could leave a novice dumbfounded. But, don’t fret. In this post, I’ll try to shed light on this and hopefully, we can understand what gesso is all about.

Encyclopaedia Britannica defines gesso (pronounced ‘jesso’) as:

“a fluid white coating, composed of plaster of paris, chalk, gypsum, or other whiting mixed with glue, applied to smooth surfaces such as wood panels, plaster, stone, or canvas to provide the ground for tempera and oil painting or for gilding and painting carved furniture and picture frames.”

Basically, gesso is a substance used to prepare or prime a canvas before you can use it in painting. It was traditionally used by oil painters so the oil paints would adhere to the canvas. Gesso is used to protect the canvas fibers, smoothen the surface, and give flexibility to the canvas.

Is there a difference between an oil gesso and an acrylic gesso? Yes, their ingredients. Traditional oil gesso, also called glue gesso, contains an animal glue binder (usually rabbit-skin glue), chalk, and white pigment. Acrylic gesso is made of an acrylic polymer medium (binder), Calcium carbonate (chalk), a pigment (Titanium white), and chemicals for flexibility and longer life.

Acrylic gesso doesn’t contain glue since acrylic paints is not corrosive, unlike oils. The glue in the glue gesso is absorbed by the fibers of the canvas which protects it from the corrosive nature of oil paints. Many artists use acrylic gesso because of its versatility, quick drying time, convenience, flexibility, and ease of use. Some artists claim that it can be used as ground when painting in oil but some argue that the flexibility of the acrylic gesso will cause the oil paint to crack over time.

An acrylic painter could choose not to use acrylic gesso if he wants the staining effect of acrylic paints on canvas. For beginners, it’s better to prime the canvas first, or use a pre-primed canvas since you are still practicing your painting skills. CanvasLot offers pre-primed canvas in various sizes so you won’t go into the trouble of priming your canvas.

If you are a beginner in oil painting, you can use acrylic gesso but just make sure that the canvas has been properly sized. If you are creating a portrait, or planning to create a masterpiece or something like an heirloom to your family, it’s better to use the oil gesso since the oil paint will stick better to it than to an acrylic.

You can buy acrylic gesso in most art supplies shops and it is available in artist quality and student quality. As with other art supplies, the artist quality acrylic gesso is more expensive and has higher quality than the student gesso. For priming a canvas, use the artist quality gesso.

What are the Solvents Used in Oil Painting?

“Solvent” is the term most commonly used to identify the liquids that are added to oil paints to temporarily change the way they work when put on canvas. Solvents dilute oil, and dissolve fats and grease from oil paints. Aside from diluting oil paints, artists use solvents to dissolve resins and clean up the work area and paint brushes.

Solvents may have different uses but they have common characteristics:

Liquid
Volatile
Produce vapors
Flammable
May be hazardous to health

You may think that you should forget using solvents since they are harmful to your health, but with proper precaution and care of use, you’ll appreciate the benefits solvents bring to a painter’s work. There are many solvents available to an oil painter but you can just select a few for your work.

Turpentine. Turpentine is the traditional solvent used in oil painting and is commonly found in hardware stores. It easily evaporates and gives off harmful vapors which causes skin irritation. When buying, choose artist quality turpentine which is colorless, since the industrial type of turpentine may contain impurities. Turpentine is mostly called as “turps” and can also be called spirit of turpentine, oil of turpentine, genuine turpentine, English turpentine, distilled turpentine, and double rectified turpentine.

Mineral Spirits. Mineral spirits or paint thinner is best used for cleaning paint brushes and thinning paints. It is less expensive and less abrasive compared to turps but it still releases harmful vapors so take precaution when using it. Mineral spirits is also called “white spirits.”

Odorless Mineral Spirits (OMS). As the name says, Odorless Mineral Spirits doesn’t have an unpleasant odor which makes it more expensive than ordinary mineral spirits. It is used for thinning paint and cleaning brushes. OMS is available in different grades, depending on the amount of aromatic properties removed from it. The more refined the OMS, the safer it becomes.

Paint thinner. Paint thinners are synthetic-based solvents. Contrary to its name, it is more effective in cleanup than as a diluting substance of oil paints.

Citrus-based thinner. Citrus-based thinner has a pleasant smell and is used to clean brushes and dilute oil paints. It has a yellowish color and a citrusy smell. Use it with oil paints to dry the painting faster. It is a more environmentally-friendly solvent than turps.

Turpenoid. Turpenoid is a popular synthetic solvent that is odorless and colorless which is used as a substitute for turps. It is great for diluting oil paints as well as cleaning brushes.

Tips for Caring and Handling Acrylic Paintings

Acrylic paints were introduced in the 1950s, much later than oils, but museums, galleries, and art collectors have included many acrylic paintings in their collections. Artists have experimented and used acrylics on canvas for its versatility of use and quick drying time. The properties of acrylic paints differ from oils so the maintenance and caring for acrylic paintings is different from oil paintings. Since acrylic paint is relatively new compared to oil paints which have been used in art for centuries, people are just starting to know its aging characteristics. For now, the best way to preserve and lengthen the life of acrylic paintings is by preventive care.

Here are the tips for caring and handling acrylic paintings:

Cleaning
Currently, there is no concrete guideline how to clean an acrylic painting. Below are just suggestions that you can do at the moment.

1. Use a clean towel or a feather duster and lightly remove the dirt on the surface of the painting. Acrylic paintings gather dust more easily than any other medium so you may have to dust them frequently.

2. If you want to keep off the dust, put the painting in a protective frame. Acrylic paintings have electrostatic charges on the surface which attracts dust and a protective frame will prevent dust from accumulating.

3. Don’t use water, soap, or household cleaners when cleaning acrylic paintings. Most cleaning agents have ammonia which can damage your painting. When you use cleaning sprays in your house, make sure that your acrylic painting is not nearby when you are cleaning to avoid excess droplets of the spray go to the paintings.

Maintenance

1. Keep acrylic paintings away from direct or extreme heat, cold, and humidity. Acrylic paint becomes soft around 60° so display your paintings far from ovens, stoves, heating lamps, or any other source of heat inside the room.

2. Don’t touch the surface of an acrylic painting. Your fingernail may accidentally leave a dent or put extra pressure on the painting which will lessen the value of the piece.

3. Mold growth is a common issue in acrylic paintings. There is no solution for it yet that would retain the original paint of the piece. The best way to lessen mold on the surface is to hang the painting in a room where there is less humidity.

Transporting

1. Put the acrylic painting in an effective packing case that would protect it from damage. According to this website, a packing case should be able to do the following:

Support the painting, insulation and cushioning foams
Protect the contents from impact and puncture without serious distortion
Maintain a sealed environment
Protect against intrusion of moisture
Provide handles for lifting and moving
Survive a multi-venue tour without compromise of any of the above functions

2. Include instructions for unpacking and repacking outside the container. The recipient may not know the proper way of unpacking the painting so proper instructions should be provided by the sender. These instructions are important especially if there is a dispute about any damage caused by shipping, unpacking, or repacking of the painting.

3. If you have to transport the painting by rolling it, here are tips:

Allow enough time for the painting to be completely cure.
Put a polyethylene plastic onto the surface of the painting before rolling.
Roll and unroll the painting at room temperature. A heated room will melt the paint while a cold room will cause cracking.
Roll the painting loosely and evenly to prevent adhesion or ferrotyping.
Once packed, secure the painting with a tape.

Checklist For a Plein Air Art Trip

Packing for a Plein Air art trip varies depending on where you’re going and the elements that you will be dealing with. There are variety of things that you must consider since you will be working outdoors. Here’s a list of the basic things you need to have on your trip.

ART MATERIALS
Since you’re going to travel, take note to have your art materials complete. It’s better if you keep things compact and organized to avoid confusion and you might forget some of your essential materials. A good idea is to invest a good art traveling bag which has multiple pockets and organizers to keep your materials intact while you’re traveling.

EASELS
Support is needed for any surface you plan to work on. And since you are traveling, a portable easel is a very good choice. Special easels comes with storage such as drawers and compartments for carrying paints and brushes within the easel. Table easels are also available if you prefer to sit while painting.

UMBRELLA and HAT
You can always find a shady area to paint but sometimes you’ll have to set up in the sun. The hat is for your protection but the umbrella is to keep the sun off your canvas and palette. A white or gray umbrella so the reflection doesn’t affect your color judgement. Try to keep both palate and canvas in the shade.

CAMERA
You can capture the initial scene with a camera. Positions of clouds and direction of the wind can constantly change outdoors so you can use this trick to make your artwork more consistent. Another advantage of the still shot is that you can use it just in case the weather turns bad and you have to finish your painting indoors.

EXTRA CLOTHING
Bring extra clothes just in case you so you can change just in case things get messy. Or you can dress in layers that you can easily take off as you get hot and put on when it gets colder. Wear neutral colored clothing to avoid too much light reflections onto your painting. Bright colors can also reflect some of their color onto your painting so stick with beige and khakis.

Now that you have your basics, here are some of the things you might want to have with you on your trip to make it more comfortable.
• Water to drink
• Light snacks
• Paper towels
• Insect repellent
• Garbage bags
• Soap and water to clean your brushes
