Customized White Opal Glass 380V Press Machine for Opal Glass Processing

1. Brief Introduction

Opal glass is a kind of glass material formed by opactifying effection produced from tiny particle in fluoride via light scatting effect. At present, the opal glass is a regularly used glass product in daily life.

Opal glass, also known as milk glass, is a distinctive type of glass notable for its opaque, milky white appearance. Its opaque and luminous properties are a result of its unique chemical composition and manufacturing process.

Opal glass tableware, with its distinctive milky-white appearance, is a popular choice for both casual and formal dining settings. Combining practicality and elegance, this unique material offers numerous advantages over traditional tableware options such as porcelain, ceramic, and stoneware.

Opal glass tableware offers the perfect blend of practicality and elegance, making it a popular choice for modern households. Its durability, non-porous surface, and microwave and dishwasher compatibility ensure it can withstand the demands of everyday use, while its timeless, sophisticated aesthetic brings a touch of refinement to any dining occasion. With its growing popularity, opal glass tableware is poised to become a staple in kitchens and dining rooms around the world.

2. Chemical composition

Opal glass is primarily composed of silica (SiO₂), sodium carbonate (Na₂CO₃), and limestone (CaCO₃). Silica serves as the main component, contributing to the basic structure of the glass, while sodium carbonate acts as a flux, lowering the melting point of silica. Limestone lends durability to the finished product. However, the true character of opal glass comes from the addition of an opacifier, most commonly bone ash (Ca₃(PO₄)₂), tin oxide (SnO₂), or arsenic (As₂O₃).

3. Manufacturing process

The production of opal glass is similar to that of common glass types, with the opacifier being the distinguishing factor. The raw materials are melted together at high temperatures, typically around 1400 to 1600 degrees Celsius, to form a homogeneous molten glass mixture. The opacifier is added during this stage to scatter light passing through the glass, rendering it translucent or opaque rather than clear.

The production of opal glass involves a combination of silica, soda, lime, and other materials, including fluorides and phosphates. These ingredients are melted at high temperatures, and then a special opacifying agent—typically bone ash, cryolite, or tin oxide—is added to give the glass its characteristic opaque, milky-white appearance. This opacifying agent scatters light, preventing it from passing through the glass and creating the desired aesthetic.

Once the molten glass mixture is ready, it can be shaped using various techniques, such as pressing, blowing, or casting. The final product is then annealed to relieve internal stresses and ensure durability.

4. Factors that influence the melting effects:

• Characteristic of raw materials
• Chemical component of batched materials
• Material feeding method
• Melting temperature

5. Advantages

• Increase the strength and thermal impacting property of the glass product.
• Increase the decoration apperance of the glass product.

6. Materials of opal glass

It is very important to use stable chemical components in the raw materials, especially the content of fluor and sodium fluosilicated, which will affect the opacifying effect.

To produce high quality product of opal glass, a high quality of silica sand shall be reqruied. The main materials to produce opal glass are below,
