Glass systems
Dichroic glass has a coating of thin layers of coloring agent that creates the effect of different colors when light interacts with the glass
Dichroic glass is made by vaporizing quartz crystal and metal oxides in a vacuum chamber and then condensing the vapor onto the glass.
Different kiln operations
fuse
slump
tack
bubble squeeze
Vitrigraph
Slumping molds - always ensure you pretreat with mold spray
Dams
Other materials that are slump temp safe - must be treated with mold spray
Artistic elements
fusing, painting with grit, multimedia (photographic, lithographic, etc)
Cutting things -
Cutters
2 kinds of snippers
Grazing Pliers
Freehand drawing, use of geometric cutting tools. Circles (of death)
Gluing things
Hairspray, tacs gels glue
WaterJet is up next for me

The coefficient of expansion (COE) of glass is a measurement of how quickly it expands and contracts when heated and cooled. Different types of glass have different COEs, and it's important to use glass with the same COE to avoid cracking and breakage:
Oceanside glass: Has a COE of 96
Bullseye glass: Has a COE of around 90
Standard window glass: Has a COE of around 84-87
Bottles: Have a COE of 82–96
Soft rods, glass, and accessories: Have a COE of 104
Here are some other things to know about glass COE:
Glass with a lower COE: Takes more time and a higher temperature to fully fuse than glass with a higher COE
Glass with a COE of 96: Is easy to cut, available in a wide range of colors, and fires well in the kiln
Glass with a COE of 90 and 96: Can be mixed using "cold fusing"
Glass from different plants: May have different COEs, even if they come from the same manufacturer
