CIBI GRANITE CUSTOMER TIP TUESDAY:
CUSTOMER GRANITE TEST
When choosing a granite for the kitchen, you need to be sure your granite is not mixed with calcite, the main component of marble and limestone. We at cibi granite process top level,high grade granite stones with the use of modern polishing methods to bring to you flawless polished surfaces. To test if a granite is good grade, bring home samples for your new counter-top and do the lemon juice and oil test.
THE LEMON JUICE AND COOKING OIL TEST
Dust your samples thoroughly, then spill a few drops of lemon juice and cooking oil on each one of them. If you notice that where the juice and the oil hit the stone its surface turns dark almost immediately, dump them. If you notice that the juice and the oil take a little time to get absorbed (a half a minute or better), then you have a stone whose absorbency can be effectively controlled with a good-quality impregnating sealer. If you notice that some samples will not absorb anything within, say, half an hour or so, this may be your stone or stones. It may not even need to be sealed. Now wipe the spills up. If there’s even a little calcite in the stone, it will react to the high acidity of the lemon juice (citric acid) and, when you wipe your spills dry, you will notice a dull spot the same shape as the drops of lemon juice. That means they can be eliminated as kitchen friendly as well. If the stone is still nice and shiny where the drops were, you have a winner.
