Durable and versatile, oil paint is a classic medium that has stood the test of time for hundreds of years. Oil colors are comprised of pigments suspended in a binder, generally linseed oil. They are very opaque, but they can be thinned to varying degrees of transparency. Oils also have a slow drying time, so artists can rework the paint for a longer amount of time.
Oil Colors contain a full pigment load suspended in a binder, generally linseed oil or another drying oil such as safflower oil, poppyseed oil, or walnut oil. Use them on stretched canvas or boards that have been primed to accept oil paints. Usually made with a single pigment, professional-grade paints mix more cleanly and have better tinting strength than lower-grade paints.
Student Grade Oil Colors have working characteristics similar to professional oils, but with lower pigment concentrations and a smaller range of colors — typically only one series. Student oils often have pigment mixes instead of single pigments, and more expensive pigments are generally replicated by hues, which may not have the same mixing characteristics as full-strength colors.
Oil paint can be packaged in both aluminum tubes and plastic tubes, and both types of packaging have their own unique advantages and disadvantages. Here are some of the key differences between oil paint in aluminum tubes and oil paint in plastic tubes:
Material: Aluminum tubes are made from metal, while plastic tubes are made from plastic.
Protection: Aluminum tubes offer better protection against light, air, and moisture, which can help preserve the quality of the paint over time. Plastic tubes are more susceptible to air and moisture, which can cause the paint to dry out or become contaminated.
Durability: Aluminum tubes are more durable than plastic tubes and can withstand more pressure without breaking or cracking. Plastic tubes are more prone to punctures and cracks, which can cause the paint to leak or dry out.
Cost: Aluminum tubes are generally more expensive than plastic tubes due to the higher cost of the materials and manufacturing process.
Size and shape: Aluminum tubes are typically smaller and more compact than plastic tubes, making them easier to store and transport. Plastic tubes can be larger and have more complex shapes, which may be more suitable for certain types of oil paint products.
Recycling: Aluminum tubes are more easily recyclable than plastic tubes, which can be an important consideration for environmentally conscious consumers.
Overall, the choice between aluminum tubes and plastic tubes will depend on factors such as the type of oil paint product, the desired level of protection, and the budget. Some artists prefer aluminum tubes for their durability and protection, while others prefer plastic tubes for their affordability and versatility.
Aluminum Tube Oil Paints:
Good at preserving the quality of paint, preventing it from drying out, and keeping it fresh for longer periods.
Aluminum tubes are lightweight and easy to handle.
The material is durable and can withstand pressure, ensuring that the paint remains intact during transportation.
The tubes can be squeezed from the bottom to the top, allowing for easy dispensing of the paint without wasting any.
The metal tube protects the paint from exposure to light and air, preventing discoloration or other degradation.
Aluminum tubes can be prone to denting or puncturing, which can result in leakage or contamination of the paint.
Some people find that the metal taste of the paint can affect the quality of the painting.
Metal tubes are not environmentally friendly and can take a long time to decompose.
Plastic Tube Oil Paints:
Plastic tubes are light and convenient to use, easy to handle, and not as prone to denting as aluminum tubes.
Plastic is affordable and environmentally friendly.
The paint remains fresh for longer periods and can be squeezed from the bottom to the top, allowing for easy dispensing without wasting any.
Some people find that plastic tubes may not preserve the paint's quality for as long as aluminum tubes.
Plastic tubes can be punctured easily, and once the paint dries out, it becomes difficult to remove.
Exposure to light and air can cause the plastic tube to degrade, affecting the paint's quality.
