Materials for pyrography
What materials you can use for burning? Burn on the CNC on any wood surfaces and leather.
The main condition for burning on a wooden surface, that it was not treated before varnish, paint or consisted of glued wood. Otherwise when burning will give off toxic smoke harmful to human health.
Selection of wood
Suitable to burn different wood, but one for the pyrography better than others.
The first tree to burn is better to take light, then it burnt the image will look better due to the maximum contrast between the picture and the tree. You can use dark wood, but keep in mind that he burnt the portrait can be lost, especially after varnishing.
The second rule is to choose the wood texture less, then You will be able to create a clean canvas for the application of the portrait of a CNC burner. Work with a pronounced texture on the tree is harder, but if the texture will fit into the design pattern, the result is very expressive.
For burning can be successfully used plywood and veneer. Plywood for making furniture can be a wonderful backdrop for almost any portrait.
A tree that has bark on the edges, looks very original! The bark creates a striking natural frame for the picture. For these paintings the most popular is saw cut basswood and Board for applied art and woodcarving.
For burning signs and functional items (box, key, etc.) a great option is a solid wood Board.
For the pyrography you can also buy items from arts and crafts shops. Many of these stores have large selection of products that are suitable for pyrography. Items that come in the form of unprocessed boxes, kitchen utensils, decorative boxes, etc.
The types of wood recommended for burning:
- Birch has an even texture and cream color
- Basswood is the best wood to burn, soft light, has ravnodenstvye texture
- Aspen – light and soft wood
Cherry – has a dense texture and pink hue
Pine – soft. It is not an easy material to burn, burn only in the course of the fibers has an average grain size. Easy to buy
Poplar – a light yellow hue and smooth texture, but has an average grain size
Buk – cream colour, the main feature silky to the touch
Pyrography on Leather
To burn the skin easier than wood. Its main drawback is the strong smell, and long preparation.
The main nichrome thread should be made less hot than for wood. Nichrome filament CNC gently sinks into the skin and gives a smooth high speed, which is not possible when burning wood.
Leather is also multipurpose, it can be as decoration to put in a frame, or for use in the home (dog collar, belt, bag). But when the burning pattern on the skin, you need to understand that the skin has such a property as to fade in the sun or bright light
Unfortunately another drawback of the skin – it is more expensive than wood and harder to buy. The skin should only buy tanned with vegetable substances, and not as chromium or treated with wax or oil.
Methods of skin treatment
There are many classifications of the skin depending on the animal’s species, age, method of processing leather, its finishes and layers. Describe the main types of skin:
- method of tanning:
fat, vegetable, chrome, Zirconia, formaldehyde, tannine and their possible combinations. The skins of vegetable processing is very expensive and thick, they are not suitable for burning. Best skins chrome tanned or combination.
- The methods for processing the front side:
smooth , brushed, embossed (used for concealment of defects of the skin), split (if sawing thick skin, in place of the front side is applied to simulate artificial real), krast, patent leather (painting skins in other colors). It is better to take the smooth skin, or crust, can be more polished.
- Leather types:
pig, sheep, goat and cattle. Here you need to choose the skin depending on your goals. Bovine leather is the straps, Calf very tender and elastic, so the most versatile. Sheepskin too soft, so is not suitable for burning, this skin will wrinkle in the folds when burning. And pigskin is porous and not beautiful.
For the pyrography, you can use the bark of trees, this is good like birch bark. It requires a delicate heating and straightening before the burning process.
Highly detailed image on the transfer tube will not work because of the softness and unevenness of the material. On this material a well to draw silhouettes and simple patterns. Before buying a tube, you need to consult that You take this pure natural cork without processing oils or any chemicals. The finished painting is then better to handle a varnish for the fact that she had not been exposed to the environment.
