The origins of grit are found in seventeenth-century Venetian technique of "seeded" with which were realized sinks, sinks, shower and terrazzo floors daincollare ground, aggianciare from the wall or support to an existing structure.

Technical information
 Our artifacts grit for technical characteristics are comparable to marble and stones. In fact they are obtained from the recomposition of natural products such as: - cement and high strength - micro fine shots of the best marbles national (carefully selected, washed and dust-) - marble dust. Being of limestone, marble grit dil offers a wide variety of shades and hues; at the same time it is easily processable and lends itself to special finishes. Its nature, makes it vulnerable to substances of acid, such as vinegar, fruit (lemon, orange, kiwi etc ..), vegetables (zucchini, eggplant, etc. ..) and cleaning products (descaling, descaling etc. ...). All these substances be to undermine the structure of marble limestone, opacizzandone significantly the surface. The natural presence of micro pores in the structure of the marble characterize a predisposition to absorb any liquid substances, which can be highlighted in halos more or less dark, depending on the type of liquid absorbed. This issue is addressed with special treatments (anti-stain treatment from simple to the most current treatments for polymers).
 Natural preservation of our products for use in interior parts subject to stains, like the kitchen, bathroom, tavern, public places (bars, restaurants, etc.) it is advisable to require treatment at our company with protective products both solvent and water, and waxes finishing oils and water-repellent. The modern chemical industry has prepared several substances suitable to waterproof and protect the stone products. Waterproofing occlude the surface making them instantly in absorbent, stain-resistant and impervious enough dirt. Given the level of absorption of grit, it is therefore necessary that the waterproof treatment, without changing the aesthetic.
 Maintenance Tips for a good conservation of the grandmother
For the kitchen
 One thing you should care. If they fall on the surface of the grit oil, lemon, orange, cola, wine vinegar etc. do not worry a lot, be sure to clean it right away and nothing will happen.

When the dough is poured in the sink should open the cold water tap in order to cushion the schok heat to the artifact. To the same end better to avoid resting directly on the shelf or on the sink a pot straight from the fire: use a trivet. If the space to clean burners cooking you must use products super degreasing, descaling, however aggressive careful not to spray these products also on the surrounding gravel. After using the sink and kitchen counters it should be dry everything with a cloth (like it's steel) so as to remove the remaining water. Which is vital if the drinking water used proves very rich in limestone.

 For bathroom

For cleaning surfaces of all products grit, as to clean the sink and shower, and 'recommended the use of a mild detergent (also water and liquid soap) without leaving it too long on the surface. Should not be used based cleaning products acids, ammonia or the like. Cleaning and hygiene of the tanks, baking soda is an excellent remedy, and should be used as an alternative to degreasing powder or spray. 5 Periodically half filled the tub sinks with cold water with the addition of baking soda and let stand for at least an hour. Sodium bicarbonate, an alkaline compound (that has a basic pH) and 'effective to remove stains, limestone and to prevent the formation of mold and eliminate persistent odors, is to restore the natural color to our. sink. To maintain a high impermeability 'grit on manufactures a simple system was used to always use white straw oil (recoverable at paint stores, hardware or shopping centers) oil applied with a cotton cloth is absorbed a short time from the surface. Today, there are alternative products capable of ensuring even better results....
