You will need
  • - knife for removing bark;
  • - enamel bucket with "ears";
  • 2.5 l pot;
  • - sheet metal 500х500х3 mm 30 holes, Ø 2.5–3 mm in the center;
  • a steel wire of length 5 m, Ø up to 3 mm;
  • - the crushed bark;
  • - bricks, stones;
  • - firewood.
In Russia tar is obtained from birch wood by the method of dry distillation at a temperature of about 650°C. If you intend to fly on your own, better use the bark of birch. Her collection will begin with the onset of the first warm spring days in may-the month or June.
To obtain 0.5 l berestovoi of tar prepare 2 kg of birch bark. In birch forests subject to cutting, choose a clean white bark with no sags and bulges. Beresta birch at this time of year is very simple. Incise with a knife birch bark from top to bottom, and it easily comes off.
You can use the bark of birch trees dead standing or fallen, but with strong enough wood. However, in this case, to fly would have a lot less. The best result you will have when removing birch bark from old trees with a diameter of about 13 cm Bark removed from birch, gather in bundles. Then, for drying, put it white side up, and then extrude.
To obtain tar, away from buildings, on level ground, dig a hole. Of stones and bricks will build a heat shield. It promotes uniform temperature distribution in the combustion zone. In a bucket, place the shredded bark of birch. Close the steel sheet (with holes in the center and a notch in the middle to collect Berestovo tar). Make sure that the bulge he was on top. On the perforated sheet with 4 holes Ø 3.5-4 mm place the pot, which will drain Berestovo tar.
The pieces of wire stretched across 4 holes, pull tight the resulting design. Sealed enclosure, apply a thick solution of clay the gap between the bucket and the metal sheet to the tar from leaking. Turn upside down the received "setup" and put it over the pit.
Overlaid wood bucket with bark. Ignite the firewood. When the temperature reaches 600-650°C Berestovo tar will be through the holes to flow into the receiving container (pot). It will take about 1.5 hours.
The resulting tar very carefully pour into a dark bottle. To prevent volatilization of nutrients, tight cap glass container. Under these conditions, the tar may be kept indefinitely.
