Get started with a fused glass jewelry project

Cut Glass

Large fused glass 2

Cut glass at a cutting station that has a fiberboard mat or felted surface, such as a blanket. First, dip Metal Glass Cutter in Cutting Oil; then score by pressing firmly (on the smooth side of the glass) along a predetermined line with the Glass Cutter.

Break Glass

Use the Glass Pliers to break the glass apart by lining the arrow on the pliers with the score, then applying pressure to the grip.

Create Design

Create a design by choosing a base piece of glass and arranging glass shapes, stringers, noodles and chunks. Stack glass no higher then 4 layers for uniform results. Stabilize the glass by using school glue between layers. Glue will burn off in the kiln. For additional effects, layer AMACO® WireMesh®, WireForm® or ArtEmboss® in Copper color only between glass sheets. (Sold separately).

Make a Jewelry Finding

With the wire provided, create a loop. Cut the wire using wire snips. Make sure the finding is a full circle shape and not a “U” shape; so that the wire will not slip out once glass is fired. Sandwich the wire loop between two pieces of glass. Leave a small area exposed; so that attachments can be made after firing.

Prepare Kiln Shelf

Carefully mix AMACO® Kiln Shelf Wash in a container. Do not create dust. Add water gradually, stirring slowly until a light creamy consistency is achieved. Apply three even coats of wash to kiln shelf. Allow each coat to dry. Place glass pieces in a single layer (with at least 1/8” between). Program the kiln for glass fuse firing

Finish The Piece

Once the kiln has cooled to room temperature, the glass is ready to be removed. In most cases, glass will be ready to use. However, finished pieces may have rough edges or kiln wash on back. Smooth rough edges with fine sandpaper and remove kiln wash with soapy water.

Importance of COE Glass

Included in AMACO® Fused Glass Jewelry Kit Glass pieces used in same firings must have the same C.O.E. rating. C.O.E. stands for coefficient of thermal expansion and relates to how the glass expands and contracts due to temperature changes. Different glass has different C.O.E. numbers. If the glass used for fusing does not have the same C.O.E number, it will crack and break. To be guaranteed compatible C.O.E. glass, buy glass from the same source and check the label to be sure that the C.O.E. is the same. All AMACO® glass has a C.O.E. of 90 and is guaranteed to be compatible.

Ceramic Kiln vs. Glass Kiln

Large fused glass 6

Although not optimal, a ceramic kiln will fire glass adequately for most school projects. Glass requires a more precise firing process than ceramics; AMACO® recommends that only Select Fire™ or computerized kilns be used to fire glass. For easy to follow step-by-step computer programming, visit www.amaco.com and download the Glass Kiln Manual.

Follow Safety Precautions

Large fused glass 8

All AMACO® lesson plans state that adults and teachers supply adequate supervision for children and students, as many art curriculums are expanding to include glass. Always use safety goggles. Safe firing instructions can be found at amaco.com or by calling AMACO® Customer Service Monday through Friday, from 8 to 5 EST.
