Metal Test Acid Kit Technoflux 5D

Scratch your item on the touchstone so that it leaves a mark.

Gold testing:

Draw a parallel line with the acid on to the metal traces. You can test multiple acids by drawing parallel lines below the first one.

We will wait for a short period of time to allow the action of the acids on the metal traces.

If the metal trace disappears, repeat the test with a lower carat acid. If, on the contrary, the mark stays intact, we can determine that its carat is the one that corresponds or is higher than the acid used.

Silver Testing:

The acid on the Silver trace should form a milky red colour. On other metals, depending on their nature, the line is completely erased, turns green or remains unchanged.

Platinum Testing:

Observe the test for one minute. The acid must not attack the platinum trail. The trace of the white gold, silver-gold alloy, and the osmium-gold alloy, will always be attacked.

Filling the bottles:

Remove the vial from the cardboard tube. With the glass vial in an upright position, apply slight lateral pressure to break the neck of the vial. Pour the acid in the designated bottle.

Advice:

It is very important to clean the touchstone with a after each use. If traces remain on the stone, the platinum acid can be used to remove them.
