Water glass casting

What is water glass casting?

Water glass casting is a process of making three-dimensional objects out of glass. It involves pouring a molten glass into a mold, which is then cooled and hardened. The result is a piece of glass that has the shape of the mold.

Water glass casting is often used to create sculptures, figurines, and other decorative objects. It can also be used to make functional objects, such as vases and bowls.

Water glass casting is a process of making a mold from a negative image. It is also known as water glass lost wax casting, or simply lost wax casting. The process begins with creating a negative image of the desired shape in a water-soluble material such as plaster.

Once the negative image is created, it is placed in a container of water. A positive mold is then created around the negative image using a water-resistant material such as silicone rubber.

Once the mold is cured, it is removed from the container and the negative image is dissolved away, leaving behind a hollow space in the shape of the desired object.

Water Glass Casting: The Art and Science of Creating Unique Metal Castings


Water glass casting is an art form that allows metal artisans to create stunning and unique pieces. At its core, water glass casting is the process of using a mixture of water and sodium silicate to create a mold that can be used to cast metal. 


This technique dates back to ancient times, but it's still highly valued today for the intricate patterns and shapes that can be achieved. Each piece cast through this process is one-of-a-kind, and the combination of art and science required to create them is truly impressive. For those looking to create something truly special, water glass casting is an excellent choice.


The Advantages and Challenges of Water Glass Casting for Metalworking


Water glass casting is a metalworking process that offers unique advantages and challenges. On the one hand, it is a cost-effective method for producing intricate metal parts with high dimensional accuracy and surface finish. On the other hand, it requires specialized equipment and expertise to control variables such as cooling rate, chemical composition, and casting speed.


Moreover, water glass casting can be brittle and prone to cracking, especially when exposed to thermal stress or mechanical pressure. Despite these challenges, many industries rely on water glass casting for their manufacturing needs, from automotive and aerospace to jewelry and art. By balancing the benefits and limitations of this technique, metalworkers can unleash their creativity and innovation, while ensuring quality and reliability in their products.
