A method is disclosed for forming an accurate stone cast from an impression of a body region, used for the purpose of prosthetic fabrication, such as dental crowns and artificial eyes and hearing aids. The initial step with this unique method is to first acquire a suitable amount of dental stone catalyst. One type of a suitable stone catalyst is calcium sulfate dihydrate. The dental stone catalyst is engaged onto the internal surface of the impression. This catalyst, placed in the area between impression material and stone, will act to hasten the initial setting of wet, mixed dental stone that is in closest proximity to the impression. The result is a stratified set of the stone. Setting of the wet, mixed dental stone occurs first at the impression / stone interface. The mixed stone better resists distortion upon setting and the resultant set stone cast is more accurate.

A method is disclosed for forming an accurate stone cast from a dental hydrocolloid impression, used for the purpose of prosthetic fabrication, such as dental prostheses. The dental stone catalyst, calcium sulfate dihydrate, is engaged onto the internal surface of set hydrocolloid impression. This catalyst, placed in the area between impression material and wet, mixed stone, will act to hasten the initial setting of dental stone that is in closest proximity to the impression. The result is a stratified set of the stone. Setting of the wet, mixed dental stone occurs first at the impression / stone interface. The setting radiates outwardly, away from the impression / stone interface. The mixed stone better resists distortion upon setting and the resultant set stone cast is more accurate.

The invention relates to a method for preparing wine. In the method, the wine base is mixed with oak particles and / or fruit cores and then boiled and refluxed to obtain the wine. Because the contact area between wine and oak particles is much larger than that of oak barrels, The wine can better absorb the color, aroma and tannin of oak. The heating and boiling operation is adopted. Compared with the static and low-temperature contact in the prior art, a large amount of steam and bubbles are generated during boiling. The bubbles contact the surface of the oak particles, which can improve the absorption of the color and aroma of the oak by the wine, and shorten the time for wine making. cycle; the wine made by the method of the present invention has better color, aroma, smaller floor space for its production and storage equipment, higher production efficiency, and reflux of condensation reduces the volatilization loss of wine in the preparation process, greatly reducing the cost .
