Method of making conglomerate engobe / 2325373
Any type of clay can be used when making conglomerate angobes, provided it can dissolve in natrium liquid glass. The clay is unfurled in water with natrium liquid glass up to 50-70% moisture. The quantity of liquid natrium glass added to the unfurled clay is equal to the quantity necessary for maximum dissolution of the watery ceramic slip with 40-45% moisture of the same clay. The unfurled clay is settled until it fully separates into sediments and a sedimental-stable suspension of clay minerals. The obtained water suspension of clay minerals, Particles of which are mot more than 1 mcm in size, are taken to the surface of the formed dry clay products, dried and are burnt in an acidic medium at temperature of 900-1050°C. An engobe-gloss coating with low water absorption capacity is obtained on the surface of the product.

1 tbl

The invention refers to compositions of ceramic masses, which can be used for manufacture of products for decorative purposes.

Famous ceramic (or black basalt Egyptian) mass of the following composition, parts: clay 500; burnt ochre 75; peroxide manganese 75 [1].

The objective of the invention is to reduce the temperature of burning products derived from ceramic material.

The technical result is achieved by the fact that ceramic material containing clay and burnt ochre, the peroxide manganese, additionally includes Krempel, liquid potassium glass and carboxymethyl cellulose in the following ratio of components, parts: clay 81,9-82,85; burnt ochre 5-10; peroxide manganese 5-10; Krempel 1-1,5; liquid potassium glass 1-1,5; carboxymethylcellulose 0,1-0,15.

The table shows the composition of the ceramic material.
