As a professional manufacturer of Glass Tile,how to check the quality is the most important step for us.Besides the one of the way to check quality by drilling or cutting on the tiles by machine. Following we will suggest one of the other best ways and also the easier way to check the glass tiles quality.

The bad quality one,as we can see,when written with ink on the backside,we can also see the ink from the front side.

The high and good quality one,when written backside with ink,it is seldomly cannot see the ink from the front side.

And also,the bad quality one,we can see the backside with diffused ink if written on it,but compared with the good one,it is with non diffused ink,and looks good effect.Why they will show so different??Just because when producing glass tiles,if the ingredient of pigment is not correct and the kilning temperature is not welled controlled ,then the quality will be bad.So if want to make high quality glass tile,we have to pay attention to these two reasons.

 

If the ingredient of pigment is controlled well enough then,we could also find the more smooth backside lacquer of the tiles.
