What is a fire polish schedule?
A suggested schedule would be: 300 degrees per hour to 1000 and hold for 20 minutes. As fast as possible ramp up to 1300 and hold for 5 minutes. As fast as possible ramp down to 900 degrees and hold for 75 minutes. Then down to 300 degrees per hour to 100 and turn the kiln off.
What is the difference between Coe 90 and 96?
The two main COEs for fusible glass are 90 and 96. The main difference between the two is that 96 is generally softer and fuses at lower temperatures than 90.
Can you fuse Coe 90 96?
Can I fuse COE 90 an COE 96 together. The difference in expansion and contraction does not sound much but it is enough to cause stress in the glass. If you fuse glass with different COEs together it might crack in the cooling process and some times even a year later. This is called incompatibility.
Can you use 96 Coe for stained glass?
You can always use fusing glass in a regular stained glass project, but you do not want to use regular stained glass in your fusing projects. If you also choose to try fusing glass with other COE numbers, you will need to keep that glass separated from the 96 COE glass.
Is all Spectrum glass COE 96?
Oceanside Compatible glass is now ALL COE 96 and made from the original Spectrum Glass formulas. Spectrum glass was also known as System 96 Compatible.
What Cone should I bisque to?
Cone 04
For example, most commercial glazes recommend bisque firing to Cone 04, and glaze firing to Cone 06 (which is cooler). The reason for this is to make sure all the carbon and other materials in the clay burn out during the bisque firing.
Who makes System 96 glass?
The System 96 family is produced in the United States by Spectrum® Glass Company (Woodinville, WA) and Uroboros® Glass Studios (Portland, OR). Spectrum and Uroboros together bring nearly 80 years of art glass manufacturing expertise to the hot glass community and the fast-growing kilnformed glass arts.
What Coe is Spectrum glass?
96 C.O.E.
Glass (100S-F) Fusible: 96 C.O.E.
What happens if you bisque fire to cone 6?
Nevertheless, if you have bisque fired to cone 6 by accident, it can make life more difficult. And here is why. The higher the temperature at which you bisque fire, the harder it is to glaze. The reason for this is that ceramics become less porous as you fire at higher temperatures.
What temperature should it be to fire polish glass?
1300°F (705°C) Fire Polish. At this temperature a thin surface of the glass has melted to produce a shiny polish like wet paint. This is hot enough to put a full shine on the glass but not yet hot enough to produce a reliable tack fuse.
Is Spectrum glass still in business?
Spectrum Glass from Woodinville, Washington, USA, closed in 2016 after failed attempts to survive the economic recession and declining demand for stained glass.
Can you bisque to 06?
The most common temperature to bisque fire pottery is cone 06 – 04. This equates to around 1830 – 1940F, (999-1060C). However, potters do bisque fire at other temperatures. The right temperature to bisque fire depends partially on the clay you are using.
