Acid polishing of lead glass
Purpose: The polishing of cut lead glass crystal is effected through the dowsing of the glass in a mixture of two separate acids, which between them etch the surface and as a result cause it to be become smooth. In order to characterise the resultant polishing the rate of surface etching must be known, but when this involves multicomponent surface reactions it becomes unclear what this rate act...
متن کاملLaser application for optical glass polishing
Fidel Vega Núria Lupón Jesús Armengol Cebrian Ferran Laguarta Universitat Politècnica de Catalunya Departament d’ Òptica I Optometria C/Violinista Vellsolà 37 08222 Terrassa, Spain E-mail: [email protected] Abstract. Rapid generation of large area polished optical surfaces by high-power CO2 laser irradiation is shown. Results focus on glasses with high expansion coefficients (a>1025/°C) conventio...
متن کاملInfluence of polishing duration on surface roughness of resin composites.
There is a need for effective polishing instruments for resin composite restorations with highly polished surfaces. The purpose of this study was to investigate the influence of polishing duration on surface roughness of light-cured resin composites. Four polishing systems, Compomaster (Shofu), Silicone Points C Type (Shofu), Super Snap (Shofu) and Enhance Finishing and Polishing System (Dentsp...
متن کاملPolishing of the Composite Resin Restorations – Literature Review
The widespread use of aesthetic f illings has highlighted their advantages and disadvantages. One of the most troublesome features of earlier aesthetic materials was the difficulty of finishing the restoration surface to decrease adherence of food debris. The rougher the finished surface, the greater the possibility of bacterial accumulation and discolouration of restoration along the restorati...
متن کاملSurface characteristics of resin composite materials after finishing and polishing.
This in vitro study determined the surface roughness (Ra) and absolute gloss (AG) values for 2 resin composites: a microhybrid and a microfill. Eight groups (n = 4) of each resin composite were prepared, along with 4 controls (Mylar strip) for the 2 resin composites. After finishing with a medium polishing disc, the specimens from each resin composite material were subjected to 7 polishing proc...
