Materials.

100 kg very finely crushed. Glass becomes very good with 500 kg of sand from weifser or other color, depending on the desired color, mixed. Become this mixture Metal oxides or the like added, depending on the measure of the desired color.

A little water is added to this mixture in order to obtain a malleable mass, and then forms balls or tablets, depending on the shape of the objects to be manufactured. These balls or boards are placed on fireproof sheets and placed in a with oven equipped with a small car.

This furnace is similar to the lehr used in glass factories.

The balls or tablets are first placed at the cold exit and then slowly afterwards moved towards the hot end. The oven is set to a sufficiently high temperature brought to soften the glass. In this state, the Balls, panels or tiles are removed from the refractory panels and placed in a mold brought, which consists of steel, iron, brass or copper.

This form is under a stamp that falls down every time you go has taken out the shaped piece and replaced it with new compound. This takes about 5 to 6 seconds.

The pieces removed from the mold are placed on top of one another in a cold room and Let it cool down as soon as the room is filled.

The same is done with silicates and porcelain earth, etc., but each earth must be special must be investigated, for the quantity of glass required for binding varies with the fusibility the materials used.

The glass additive or the more or less easily meltable flux is depending on the Nature composed of earthy materials or silicates. The inventor avoids as much as possible the use of lead "and uses mostly alkaline products.

To achieve the purest white, broken porcelain is used, which is very fine is pulverized; one then proceeds with it as with the sand, and receives goods that are completely resemble ordinary porcelain.

The fluxes, which are used to bind the substances used, can be added to the raw mixtures required for their image are added; however, it is more advantageous to make the mixture with already melted fluxes, because you save time and the results are safer.

Using this method, drain pipes and other pipes, stone feet, tiles, Firebacks, statuettes, decorative ornaments

for buildings, paving stones for streets, bricks for roofing houses, and bricks used in Water or used in damp places.

Claims (1)

Patent claim:
Process for the production of goods by mixing the powder of difficult-to-melt substances such as sand, porcelain, etc., with glass powder and some water, shaping the mass in the form of spheres or plates, heating the spheres or plates until the glass softens, and pressing them in the form of commodities and cooling them.
