You can keep staring or wait for 10 – 15 min,

During the test, you should not go away. By the time you come back, the bubble reaction might already be over.

Bubble reaction? Why does this happen?

This stone does not have enough quartz content and contains too much stone or lime powder. The more it had, the faster you could see the bubble reaction.

Second, this stone was coated with a sealant on the surface to make it shiny. It will create a bubble reaction too.

Either one, it is not the quartz stone you’re seeking for,

After wiping the Harpic,

  1. A layer of sealant is gone
  2. Become rough surface, the tiny hole can be see by human eyes now
  3. Colour faded
  4. Discolouration

This is the result you should look for. No chemical or bubble reaction on quartz stone.
