Opaque paint boxes put to the test

All the winner needs is a name plate...

The girls of class 10a in the Regional School in Rülzheim tested opaque paint boxes and won the first prize in the competition "Youth Researches" staged by the Stiftung Warentest (foundation for product testing). This edition of Teacher Info shows you with which methods and amazing machines 3 girls tested the various paint boxes. At the end of the project the girls were able to answer an important question: "Can 74% of the teaching staff be mistaken in their recommendation for opaque paint boxes?"


The idea

For more than 10 years Kerstin, Nada and Sarah from the Regional School in Rülzheim have been working with opaque paint boxes so the idea to choose this object for closer examination does not seem remote, however it was co-incidence: as they were clearing out old cupboards, paint boxes belonging to many school generations came to light. The girls asked themselves why their fellow pupils lost interest in these old paint boxes? The reasons were apparent: empty colour pans, broken hinges and dirty casing made an uninviting impression. That is how the idea to test paint boxes was born.


Till then, machines or tools for analyisis build by pupils for the testing of paint boxes did not exist. That's why very early on, the plans for the first machine were made.

The girls wanted to test and evaluate a total of 14 product characteristics. In addition to their own tests, the young girls sent out 120 questionnaires to art teachers in a total of 60 schools.



The test series

14 opaque paint boxes from various manufacturers were examined.The final judgement would depend on the following criteria:

  1. Declaration (e.g. adherence to DIN norm)
  2. General product characteristics
  3. Case (e.g. number of mixing pans, sensibility to knocks)
  4. Quality of the paints (e.g. opacity)

Examination of the paint quality

Once they were ready to start, Kerstin, Nada and Sarah tested the damage caused to the paint pans by falling a ball and the quality of the paint pans with machines.

To assess the opacity of a paint, the girls painted so called greyscales.

The young scientists also tested the adherence to the DIN Norm 5023. This defines the quantity of paint in each pan.

The Evaluation

The evaluation of the tests by computer

Kerstin, Nada and Sarah use modern computer technology to record all the results. All 14 paint boxes which were tested were brought into line and given an overall score. In addition, the girls worked on recommendatios for the improvement of serveral of the boxes. One suggestion was, to provide the winner of the test with a name plate to avoid confusion. The budding young scientists sent in the whole project to the competition "Youth Researches" in Berlin. Their teacher, Mr. Adler and their fellow pupils in class 10a were of course enormously pleased that the 3 girls won first prize.

The winner of the test

K12, the winner of the competition for testing opaque paint boxes

Pelikan is thrilled about the test results. For over 50 years, the Pelikan K12 Opaque Paint Box has been the pupil's most reliable companion - in art lessons and at home. It is appreciated by many for its unmistakable competence as a pre-condition for works of quality.74%. That is probably why 74% of the teachers questioned by the 3 school girls recommend the Pelikan Opaque Paint Box K12 for use in their lessons.

By the way: The winner of the test is now available with name plate.
