Being a natural product that is kiln fired, there will always be some tiles in each batch that show some imperfections.
Tiles are sorted at the factory before packaging, and any with visible imperfections are removed and graded to be sold as seconds. A few will always slip through the system. These tiles are perfectly sound, but are imperfect all the same.
The international standards allow 5% of any first grade consignment to have some visual imperfections. There are a few factories that will allow up to 15%. An allowance of 5% means that in each group of 100 tiles, there may be up to 5 tiles that show some imperfections. The tiler will always put these tiles aside and use them when a cut tile is needed.
If you have a tiling project that has obvious imperfect tiles installed (like some glaze missing on the edges), then it is simply because the tiler has not checked the tiles as he laid them.
Defect tiles can slip through the factory. Faults such as missing glaze on the edges of a tile, firing cracks, craters, bubbles, pinholes, smudged patterns, etc. are all visible things and the installer should put these tiles aside and not use them.
If the tiles have not been installed, just take them back to the Ranjanas Ceramic Branch from which you purchased them and we will swap over the stock. If you prefer, we will credit them.
If the tiles have been installed, we will supply you with replacements for the affected tiles. Your tiler will need to remove the faulty tiles and install the new ones. Visually imperfect tiles should never be installed unless specifically requested by the owner.
Check the side of the box for the printed batch number, so we can supply tiles that match the shade of your other tiles. Unfortunately, we won't cover the costs to remove and reinstall these tiles. No repair claim can be made to Ranjanas Ceramic once the tiles have been laid.
