After the wash day is known before the wash day: one has been spitting all day and now you should actually wash out the concentrate. What is usually done wrong now is that the material is not screened. This makes the washout much easier (see book!)


The washing out of fine gold can quickly become agonizing if some basic rules are disregarded (see book). The most important rule is that the washing out of different dense (not heavy) bodies is easy when these bodies are all equally large. The principle is: heavily displaced easily. The problem is, however, that most commercially available sieves are much too coarse or have a poor gradation.

We recommend the following procedure: First a coarse screening is carried out. Anything remaining in the sieve is washed by hand in the pan. We would start with a 2mm screen. The washing out of the fraction larger than 2mm goes with the pan like the flash (the fine stuff has fallen through the screen and is later processed). This is followed by a second sieving, for which the expected gold size must now be known approximately. Example:

I expect a flare size of 1mm. If I now cast on 1mm, I will lose quite exactly 50% of the gold. Why? The gold is only 1mm in average. A tinsel has e.g. 0.9mm (which would go through), another 1.1mm (which would get stuck). So you should not with the flare size seven, but with a "too small" and a "too large" screen. The keyword for all Wikipedians is the "Normal distribution" . It is thus expected that most of the tufts are e.g. 1mm, but there are also 0.5mm and 1.5mm respectively (only in a much smaller number!) The procedure should be as follows: If the expected lattice size is 1mm, we have the "large" fraction with a double sieve size = 2mm), the "small" fraction with half the sieve size (= 0.5mm), and then the "medium" fraction (smaller 2mm but larger 0.5mm) is obtained in the 0.5mm screen (In this example, I would wash> 2mm simply by hand with the pan), but the "small" fraction can be washed out separately from the "middle" fraction much easier Still too big, this can now be divided again with the "middle" sieve, which in turn simplifies the wash-out process (only in the case of a really large quantity in this fraction.)

Suggested screen selection:

  • Expected flare size larger than 2mm: Be ashamed! This is easy with the pan!
  • Expected flare size 2mm: fine screen 1mm + fine screen 2mm (the flare> 2mm then go into the pre-screening fraction)
  • Expected flitter size 1mm: fine screen 2mm + fine screen 0.5mm (possibly: fine screen 1mm)
  • Expected flitter size 0.5mm: fine screen 1mm + fine screen 0.2mm (possibly: fine screen 0.5mm)
  • Expected flare size 0.2mm: fine screen 0.5mm + fine screen 0.2mm.
  • Expected flitter size <0.2mm: fine sieve 0.2mm, possibly fine sieve 0.5mm to secure concentrate on "outlier" upwards


  • Diameter inside approx. 20cm, diameter outside approx. 21cmm
  • Height approx. 6cm
  • Wall thickness approx. 5mm (double-walled, interior hollow!)
  • Double-walled stainless steel, glued with silicone
  • Stainless steel screen. Sieve is spot welded
  • All flanges and edges are rounded and therefore not sharp
  • Sieves are stackable (but not sealed, water can escape between the sieves)
  • Weight approx. 300g
  • Permeable area at least 40%

Explanation of options

  • Size: . Please specify the desired size. The numbers indicate the internal spacing of the screen grid (ie not ) the meshsize. Example: A wire lattice with a wire thickness of 1mm, where every 10mm is a wire, has an inner distance of 0.9mm and A meshsize of 10mm)


Please note the special prices for a double or quad pack! This advantage can not be granted if two or four individual sieves are purchased!

For the books, our Goldwashbuch is most warmly recommended (and not only by ourselves, see there!). It outlines, with many illustrations, the most important techniques of gold searching and presents some of the most important tools in comparison. The book can be delivered free of charge!
