Types of brushes.There are so many many brushes:washes/glazes, rounds, flats, filberts and liners and more. Choosing the right type for the technique is important. Let`s look at the different types.Flat Brushes-Flats are brushes with a straight chisel edge and square shaped filaments. These can be known as shades if they`re in smaller sizes and washes/glazes if in bigger sizes. Large areas are painted with a wash/glaze brush whereas smaller flats are used for small areas of painting. Round brushes-Round brushes have a large diameter of the ferrule, more so than a liner, which can be used for applying thick to thin lines, filling in odd shaped areas, painting details and work great for lettering. Liners don`t hold as much paint as a round, however, they are super great for creating lines or curves. Script liners are similar to liners but the filaments are much longer and hold more paint. A round brush tapers to a pointed tip – several types of rounds are referred to rounds, liners or script liners. Angle brushes are filaments that have been cut on an angle – these are excellent to use in small or curved areas of the painting.Filberts Brushes with oval shaped filaments are known as filberts in smaller sizes and oval wash in larger sizes. Both shapes can be used for base coating, stroke work and more. There are filbert combs, filbert wash and more.Mop Brushes,Then there are mop brushes–great for blending and smoothing out small areas. They`re also ideal for applying powdered pigments–just dust them lightly over hot or tacky wax.Specialty Brushes-Then there are all the speciality brushes on the market used for certain techniques and garner their own results–fan, deer-foot, stumbler, mops,stencil and more.

North American spruce is impressive, as is the case with the wood it produces. Among all the tree species in the world, North American spruce has the highest strength-to-weight ratio. Elastic with good toughness resilience, able to withstand sudden loads. As the narrower sapwood of North American spruce gradually blends into the heartwood, there is no obvious transition, so the appearance is beautiful. The color of the wood ranges from milky white to slightly pale pink, odorless and tasteless. North American spruce has become a famous reprocessing wood for its excellent processing properties. It is easy to dry and is dimensionally stable after drying and is not susceptible to warping or distortion. Due to its long fiber length, straight texture and soft texture, North American spruce is well machined to meet fine tolerance requirements and to securely grip various fasteners. North American spruce is easy to plan, and the surface after smoothing is smooth, bright, and crack-free. At the same time, it absorbs paints and colorants very well. Due to its uniform color, it requires less paint than other woods and is easy to bond.
Second, the physical properties of North American spruce
Apparent density 430kg (kg/m3)
The compressive strength of the grain is 37.8 (MPa)
Horizontal grain compressive strength 4.1 (MPa)
Bending strength 69.5 (MPa)
Shear strength 9.2 (MPa)
Splitting strength 38.0 (MPa)
North American spruce is known for its use in aircraft and ships due to its high strength-to-weight ratio and good shock absorption. Ship masts, booms, crossbars and structural keels can be made. Due to its excellent strength without adding excessive weight, it is widely used in various rowing boats from single rowing to offshore speedboats. Particularly suitable for use as a paddle.
The strength, lightness and excellent elastic resilience of North American spruce make it one of the best woods for ladders. At the same time, its good processing properties have become a highly respected wood variety for the production of special joinery products such as interior finishes and sliding screens. Due to its long wood fiber, excellent resonance, stable size and good gluing properties, North American pine is often used to make high quality musical instrument soundboards. In addition, it is also a well-respected building material. Because it can withstand wind and rain and is evenly deformed and not easy to crack, it is often used to make seats for outdoor stadiums.
