A putty knife is a specialized tool used when glazing single glazed windows, to work putty around the edges of each pane of glass. An experienced glazer will apply the putty by hand, and then smooth it with the knife. Modern insulated glazing may use other ways of securing the glass to the window frame.
While the standard double glazing is most widely used, triple glazing is not uncommon, and quadruple glazing is produced for cold environments such as Alaska or Scandinavia. [17] [18] Even quintuple and six-pane glazing (four or five cavities) is available - with mid-pane insulation factors equivalent to walls. [19] [20] [21]
Crazing is a spider web pattern of cracks penetrating the glaze. It is caused by tensile stresses greater than the glaze is able to withstand. [1] [2] Common reasons for such stresses are: a mismatch between the thermal expansions of glaze and body; from moisture expansion of the body; and in the case of glazed tiles fixed to a wall, movement of the wall or of the bonding material used to fix ...
Scumble is a technique similar to glazing, except that the coating is opaque, and is just painted on very thinly to allow bits of the paint below to shine through. Scumbling works by a principle similar to that used by pointillists, mixing colors optically. While most painters glaze with dark colors, scumbling is more popularly used for lighter ...
A matured lime putty is thixotropic, meaning that when a lime putty is agitated it changes from a putty into a more liquid state.

Glass casting is the process in which glass objects are cast by directing molten glass into a mould where it solidifies. The technique has been used since the Egyptian period. . Modern cast glass is formed by a variety of processes such as kiln casting, or casting into sand, graphite or metal moul
