HOW TO REALIZE DYE STONE

1.Dye Black Stone 

Some dyed stone when be sold to customers will not be distinguishable if the worker does not specify: black stone also has many black stones dyed with cheap price ... if you buy black stone, you should choose basalt black, Mongolian black, Hue black, kim sa bran..not buy dyed black, starlight black ....

The color of black after a short time will change to patchy, not to mention that this dye is an industrial dye that has not been tested for its toxicity or susceptibility to water or environment. Most of these dyes are imported from China where the conscience of businessmen is alarming. For black stone to increase profits or compete cheaply, many places mix dyed stone and natural stone even completely dyed stone. With stained black stone, after a while the black will turn gray and your feet and mops will always be black

2.To distinguish between natural stones and dyed stones, the following points should be noted:

- The back side of the natural stone is gray white of the stone and translucent (because it is not polished). In addition, there are black dots and patterns of hidden rocks.

- The back side of the dyed stone is dyed and no longer see the faint white gray of the natural stone. This is a technology that embeds a stone slab into a dye chemical.

- Take the broken rock and look at the edge of the stone, if the stone is dyed we will see the dye penetrate a layer and have a darker color than the natural stone. This is dyeing by one-sided dyeing technology.

And note when buying stones that are pure black or absolute yellow, there must be a clear agreement in the guarantee of color fastness. For advanced "whole" dyeing technology from large Chinese factories, it is very difficult to know, only can recognize after the using time

3.Some basic disadvantages of dyed stone compared to natural stone

+ The lifespan of dyed stone is much shorter than natural granite, the gloss is also significantly reduced after a short use.

+ Color is the most confusing thing between these two rocks. However, the degree of staining is very fast fading and even that fading has a negative impact on the health of the user because the chemicals to dye do not have a clear origin. If you decide to use dyed stone instead of natural stone, ask the store a warranty for the color product. Because there are many cheap and poor quality dyed stone products on the market.
