Paradise Paint - A specially formulated glass paint, which will not loose color when, exposed to the intense heat of molten glass. Paradise paint is often used to decorate pieces created using encased painting or graal techniques.

Parison - The first "gather" of glass gathered at the end of a blowpipe.

Pattern Mould - Pre-shaped patterned on the molten glass before the bubble is blown.

Pegging - Placing a Parison (small air bubble) into a gathering pit.

Pick-up Decoration - A technique whereby a hot parison is rolled in chips of glass, which are picked up, marvered, and inflated.

Pipe - A long hollow steel rod used in glass blowing. By blowing through the pipe, the glass is formed into the preliminary shape. Sometimes referred to as a “rod”.

Plate Glass - Flat glass made by the casting or rolling of molten glass which is then mechanically ground and polished to produce a smooth and transparent sheet.

Polishing - Buffing or smoothing the surface of a glass object to a bright clear luster when it is cold by holding it against a rotating wheel fed with a fine abrasive. Glass can also be polished with hand-held tools.

Polishing Wheel - Traditionally made of wood or bristle and more recently of cork, polyurethane and bonded cloth, these discs are used in conjunction with abrasive pastes to polish glass surfaces. Felt wheels with material such as cerium oxide and other commercially produced powders are now widely used for fine polishing. In the polishing process, the wheel is rotated at speed by means of a motor and applied to the glass to be polished.

Pontil - The pontil, or punty, is a solid metal rod that is usually tipped with a wad of hot glass, and then applied to the base of a vessel to hold it during manufacture. Once the Pontil is removed, a "punty mark" is left.

Pot - A fire clay container placed in the furnace in which the batch of glass, raw materials used to make glass, is continually kept at a designated heat for gathering. The glass worker gathers directly from the pot.

Powder - Colored glass that has been pulverized into a fine powder.

Power - Is the ground glass that is put into the Pot for melting the final molten glass that will be used by the hot glass workers.

Punty - Is the hot glass or gathering that is placed on the receiving pipe for transferring the glasswork that is currently connected to the blowpipe. The technique used to change the end of the glass that is being worked on.
