Dishwasher corrosion of glass and the resulting formation of unacceptable appearance limits the lifetime of glass tableware in private households and even more in professional catering business where constant replacement of glass tableware is a considerable cost factor.
Introduction Although glass is considered to be a material with high chemical durability, when contacted with water vapor, glass articles may undergo some changes at the surface because of atmospheric corrosion which is also called "weathering" effect due to unsuitable warehouse or household stock conditions.

With regard to water and oil emulsification, there are two basic types of emulsions: water-in-oil emulsion and the oil-in-water emulsion.
Surfactants with low HLB value are normally required for water-in-oil emulsions and surfactants of high HLB value are normally utilized for oil-in-water emulsions.
De-ionized water was used for brine solution preparation.

Since Ming dynasty, following the development of handicraft silk Chengze and Shengze became the professional silk towns.

PLA does not cause allergic reactions and does not provoke tissue rejection, does not have the property to accumulate in the tissues and is removed very easily, decomposing into carbon dioxide and water PLA is generally degraded in two stages: first, it is hydrolyzed to lactic acid, which then turns into pyruvic acid under the action of lactate dehydrogenase, and then enters the mitochondria and is completely oxidized and decomposed to form carbon dioxide and water [1].

A 0.2-g powder of sample was extracted with 100.0 ml 70% ethanol in an ultrasonic water bath for 30 min.
The mobile phase consisted of acetonitrile(A) and 0.05% phosphoric acid in deionized water (B) using gradient program of 19% (A) and 81% (B) in 0—8min,19→50% (A) and 81→50 (B) in 8—35min, 50→100% (A) and 50→0%(B) in 35—36 min, 100→19%(A) and 0→81% (B) in 36—40 min.

The reduction of water content of samples contributes to preserve the raw matter preventing the degradation during storage and transportation.
Moreover, drying reduces the transport cost and avoid the interference of water on the subsequent extraction process decreasing the need for solvent [6].
The convective air drying is one of the most used techniques to reduce the water content of food [7].
For that purpose, the Generalized Reduced Gradient (GRG) optimization method, available in the Microsoft Excel spreadsheet from Microsoft Office XP Professional, was used.
The initial moisture content of samples was 0.482±0.006 kg water/kg dry matter.
