Quality : Information
- Material Quality & Quarrying Techniques
- Granite supplied to you direct from our own quarries allows us to offer our customers the best products at extremely competitive prices. All granite tiles from Eurasian are carefully calibrated, bevelled and polished. We also process only the best quality granite slabs and countertops.
- Be very sceptical of companies claiming to have hundreds of quarries!
- Prices are for first quality material only.
- A wide selection with your choice of delivery schedule.
- Modern quarrying techniques with blocks extracted using proven methods. We do not dynamite/blast any of our quarries which can cause hairline cracks in the material.
- The first Indian company to import, adopt and use European production machinery more than 30 years ago with processing machines from France, Germany, Italy and Japan. All machines use water cutting, see below.
Quality : Water V. Kerosene Cutting
- Eurasian uses water exclusively as a cutting agent for all granite products. Granite tiles and slabs are normally processed by using water as a medium for cutting. This is the industry accepted method for processing granite. However, there are many manufacturers that use kerosene in place of water as a medium for cutting, then soak the granite in water to remove the kerosene from the surface.
- Although the kerosene cannot be seen on the surface, because granite is porous, the kerosene remains within the granite. Using kerosene in place of water increases the life of the diamond tools used in processing the granite by 20%-30%. This allows the end prices of the granite to be lower for material processed with kerosene, but results in an inferior product for the following reasons:
- When kerosene is absorbed by granite, it will trigger the dormant ferrous and ferric particles in the minerals. Once these latent particles are triggered, the chemicals formed will eventually find their way out of the polished surface, creating discolorations and pit holes.
- The polished surface, which normally lasts for years, will begin showing dull patches within 18 to 24 months on kerosene processed granite. In many cases the polish is lost on the entire batch of granite giving a honed rather than polished finish.
- When kerosene processed granite is used over radiant heating systems, the kerosene will slowly evaporate out of the granite causing health hazards and unpleasant odors.
- Ensure when comparing prices and quality that you are comparing like with like.
Quality : International Standards
- The depth of polish will be a minimum 95%.
- Slab lengths and widths will be given a 2cm allowance from the narrowest point of measurement.
- Since granite is a natural product it is not possible to give guaranteed lengths and widths, however you will always be offered the estimated slab measurements before sawing blocks to decide whether those slabs are suitable for your purposes.
- Slabs that are in stock ready for shipment will already have been measured. These can be independently inspected and verified if required.
- Materials with natural open-veined formation will have a suitable resin filler applied.
- The thickness of gang sawn slabs will have a tolerance of +/-1/2mm, the polished face will be level.
- Tiles are produced to +/-0.1/2mm.
- Colour enhancers are not used unless specifically requested.
Quality : The difference between First Choice, Commercial Quality and Second Quality
- First Choice materials is exactly that. When you receive it all you should need to do when fabricating is to cut to size, profile whatever needs to be done etc. The polishing should be of a high gloss and there should be no visual defects in the material. Wastage should be low.
- Commercial Quality usually means that the polish is not quite as good and that there will be some obvious defects such as small natural hairline cracks and maybe some blotches in the material. A good sawyer and fabricator can use the slab to his best advantage however, obviously, a reasonable trade knowledge is required to get the best out of the slabs.
- A great many slabs seen in the USA are actually Commercial Choice and not First Quality as purported. There is nothing wrong with Commercial Choice material. Most companies buying on price buy this quality without even knowing it!
- Second Quality should really only be used for large scale contracts unless specifically requested where the slabs are to be cut into smaller modules. There will be many repairable natural defects and, most likely, blotches in the material. For experienced fabricators this can be a great way to save money on raw material costs however the extra time taken to make best use of the material must be taken into account.
- Buying Second Quality should only be done either by self-inspection or by a trusted inspector. Wastage could be high especially if considered for use as counter tops.
- Caveat Emptor - Buyer beware!
