Molds for glass fusing

Types of molds for glass fusing

Molds for glass fusing are used to shape and form glass when it is melted and fused together. These molds are typically made from materials that can withstand high temperatures, such as kiln-safe ceramics or special mold powders. They come in various types, including:

• Slump Molds

  Slump molds are shapes that glass can be made to fit over or slump into when it is fused and fired in a kiln. They are used to create bowls, plates, and other shaped glass objects. Slump molds come in various shapes and sizes, allowing for many different glass pieces. Some common types of slump molds include:

  Pottery molds - these molds are used to create pottery shapes that glass can slump into. They are usually made from ceramic materials that can withstand the kiln's heat.

  Plaster molds - these molds are made from plaster and used for various pottery shapes. The glass can slump into plaster molds as long as they are properly prepared.

  Silicone molds - slump molds made from silicone can be used with glass that is slumped at lower temperatures. Silicone molds are convenient since they allow for easy removal of the slumped glass pieces.

• Pressed Molds

  Pressed molds are designed for glass to be pressed into shape using heat and pressure. This method creates detailed and solid glass pieces. Pressed molds are often used for producing glass items in bulk since the pressing technique allows for high precision and strength in the final products. Additionally, because the glass is pressed into the mold, a lot of detail can be achieved that would be challenging with other forming methods.

• Drop-Out Molds

  Drop-out molds are a type of glass fusing mold where the glass is shaped by dropping it directly into a mold cavity. Once the glass has been fully melted in the kiln, it is poured into the mold, and gravity takes care of the rest. As it flows, it will take on the shape of the mold cavity. The glass is then left to cool and harden into the desired shape. Drop-out molds create pieces with nice, clean edges since no glass drips or spills over the rim.

• Cabochon Molds

  Cabochon molds are specialized shapes that glass can be fused into without any holes or bumps. These shapes are smooth and rounded, perfect for setting into jewelry pieces. Cabochon molds come in many different sizes and designs so that unique cabochon pieces can be made. The glass used in cabochons is typically slumped at a lower temperature since no intricate patterns need to be pressed or fused.

Features and Functions of Molds for Glass Fusing

Molds for glass fusing are specially designed forms or matrices into which glass pieces are placed and fused together in a kiln to create shapes and objects. These molds have different features and functions as described below:

• Material

  Fusing molds are usually made from materials that can withstand high temperatures without melting or deforming. They include:
  -Ceramic: This is the most popular material used in making fusing molds. Ceramic molds are durable and provide even heat distribution, which is crucial for glass fusing. They can also withstand repeated use in high-temperature kilns.
  -Steel: Steel molds are also used for glass fusing. They are strong and can be shaped into complex designs. Steel molds are easy to maintain and provide consistent results.
  -Silicone: Silicone molds are flexible, making it easy to remove the fused glass without breaking. They are great for creating intricate designs and patterns.
  -Graphite: Graphite molds are used where a smooth finish is required. They offer excellent release properties and can withstand high temperatures.

• Shape and Design

  Fusing molds come in different shapes and designs to create various objects. They can be shaped like bowls, platters, vases, or more intricate designs like sculptures and decorative pieces. The design of the mold determines the shape and texture of the final fused glass product.

• Size

  Molds for glass fusing can vary in size from small molds used for pendants and earrings to large-scale molds used for big glass art pieces or functional items like glass tabletops. The size of the mold directly impacts the size of the final product.

• Non-Stick Surface

  Many molds have a non-stick surface to ensure easy removal of the fused glass without damaging it. This is crucial, especially for intricate designs where sticking could lead to breakage or deformation of the final product.

• Heat Resistance

  All fusing molds must be able to withstand the high temperatures of kilns used in the glass fusing process. These molds are constructed with materials that can handle extreme heat without failing.

• Customization

  Some glass fusing molds allow for customization. Users can create unique molds to fit specific projects or artistic visions. This feature is especially beneficial for professional glass artists who require molds for specific designs.

Molds for Glass Fusing Q & A

Q1: How to prevent the glass from sticking to the mold during fusing?

A1: To prevent glass from sticking to the mold, use kiln release. It is a spray that is applied to the mold before placing glass. The spray forms a barrier between the glass and the mold. It makes sure the glass comes off the mold easily after cooling.

Q2: How does one clean molds for glass fusing?

A2: Molds should be cleaned after every use to increase their lifespan. Use a soft brush and water to remove any dirt or debris. If there is stuck glass, use a scraper to remove it gently. Avoid using harsh chemicals that might damage the mold.

Q3: Can one use regular oven instead of kiln for glass fusing?

A3: No, regular ovens can't be used for glass fusing. Glass can only be fused using a kiln. A kiln is specifically designed to fuse glass. It provides controlled temperatures that are evenly distributed. A regular oven can't reach the high temperatures required nor distribute them evenly. As a result, the glass would be either poorly fused or not fused at all.

Q4: What types of glass can be used with fusing molds?

A4: Fusing molds can be used with art glass or float glass. Art glasses include stained, colored, and opaque glasses. These glasses are specially made for glass fusing.

Q5: Can molds be used for purposes other than glass fusing?

A5: Most molds can only be used for glass fusing. Using molds for other purposes can damage them. Always read the manufacturer's guidelines to understand the uses of the mold.
