I have heard that this can be done, for assessments in respect of hardness/softness of materials by using the 'Sprailloof' method.
Can anyone tell me what it is?

I always thought April Fool's were meant to be done before 12 midday!

Apart from april fools, I don't know the sprailrooof formula but for calculating specific densities we compared the weight of a defined volume of water to that of the same defined volume containing a material of different density. 100 cc of water equals 100 gramme. 100 cc volume containing a precise weight of another material suspended in the water has a different weight. From the diference in weight you can calculate the specific gravity of that material. With a bit of thought I might come up with the formula. But I'm sure you don't need that much help

What has density got to do with the hardness or softness of a material. You can have very hard materials with low or high densities etc.
I think your terminology is slightly off beam.
Density is mass per unit of volume or a measure of a materials compactness!!!!
