What is the meaning of devitrification?

What is the meaning of devitrification?

devitrification, process by which glassy substances change their structure into that of crystalline solids. Glass is formed by the cooling of a rock magma too rapidly for this structural regularity to become established.

What causes devitrification in glass?

Devitrification can occur when heating your glass for too long at a high temperature. The glass looses its glossy appeal and becomes dull or crinkled on the surface. Some people call this whitish scum, crazing. This is really the glass molecules changing their structure to crystalline solids.

What is Devit in glass fusing?

Devitrification (“devit”) is the growth of crystalline structures within or on the surface of glass. Devit can result from firing too slowly through the devitrification range of temperatures. It can also result from firing contaminants like oils and fingerprints onto glass and thus seeding the growth of crystals.

How is devitrification treated in glass?

Applying devit spray and refiring can also be effective. Alternatively, sandblasting, acid bath, or polishing with a pumice stone or rotary brush can be used to remove the unwanted surface.

How do you get Devitrification?

Devitrification Solution

1. 1 quart (4 cups) distilled water.
2. 1/4 cup 20 “Mule Team Borax” (available at most grocery stores in the laundry detergent section)
3. 2 Tablespoons Fuse It Tack Film or other clean burning glass glue,

What does Detrify mean?

verb (used with object), de·ni·tri·fied, de·ni·tri·fy·ing. Chemistry. to remove nitrogen or nitrogen compounds from. to reduce (nitrates) to nitrites, ammonia, and free nitrogen, as in soil by microorganisms.

How do I uninstall Devit?

If your glass is flat, you can sift a very thin layer of Clear powder (about 2 grains thick) over the entire piece and fire it to 1425°F (774°C) – 1450°F (788°C) for about ten minutes, depending on your kiln. This should remove the visible presence of devitrification.

What is Devit spray?

It is a low melting clear glass powder that creates a cap to keep oxygen away from the base glass thus eliminating devit. (Devit requires time, temperature and oxygen). Clear Coat is used mainly on float/window glass.

What does instigator mean?

The instigator of an event is the person who causes it to happen. He was accused of being the main instigator of the coup. [ + of] …the key instigators of reform. Synonyms: ringleader, inciter, motivator, leader More Synonyms of instigator.

How do you get devitrification?

How do you use Fuse Master Super Spray?

Super Spray Overglaze For easy application, simply brush it onto your glass project or spray it on with an air brush or atomizer BEFORE THE FIRST FIRING. Matures at 1350F or higher. Super Spray is not designed to FIX existing devitrification.

What is devitrification or devit?

What is devitrification or “devit”? Devitrification (“devit”) is the growth of crystalline structures within or on the surface of glass. (“Vitri” = glass; “devitrification” = the process of becoming un-glasslike).

What does devit mean in glass?

Devitrification (“devit”) is the growth of crystalline structures within or on the surface of glass. (“Vitri” = glass; “devitrification” = the process of becoming un-glasslike). Devit can result from firing too slowly through the devitrification range of temperatures.

What is Vitri and devitification?

(“Vitri” = glass; “devitrification” = the process of becoming un-glasslike). Devit can result from firing too slowly through the devitrification range of temperatures. It can also result from firing contaminants like oils and fingerprints onto glass and thus seeding the growth of crystals.

Can devitrification be used in glass art?

While this condition is normally undesired, in glass art it is possible to use devitrification as a deliberate artistic technique. Causes of devitrification, commonly referred to as “devit”, can include holding a high temperature for too long, which causes the nucleation of crystals.
