Glossary
304 Stainless steel - The most common stainless steel alloy. It can be used only for some bodies and mouthpieces, but not for heads. 310 Stainless steel - One of the best performing alloys of high temperature stainless steel available. It has a higher nickel content than 309, which helps it resist oxidation at high temperatures. 316 Stainless steel - A grade of Stainless with molybdenum, which help to resist certain kinds of chlorides. This is the best material available for making bodies because it's slightly stiffer than 304, but not acceptable for heads. 4130 Steel - Also known as chromoly. This is steel with the addition of chromium and molybdenum. It is much stiffer than standard mild steel and more resistant to rusting. It can crack and warp if overheated. Acetal - Technically there are two types of Acetal, copolymer and homopolymer. Delrin is made from homopolymer acetal resin and Acetron GP is made from copolymer acetal resin. These materials are used to make mouthpieces. Bagnaor - Pronounced (ban-YA-or). Bagnor is from the Italian - Bagnare : to soak. This tool looks like a closed back puffer - it fills with water which can be used to quench a moile. Balloton - Pronounced (bal-o-TON). Also known as a pineapple mold. It is used to create a regular pattern of bubbles in glass. Borselle - Also known as jacks, used to shape and cool glass. The thinner the blades, the less cooling effect they have on the surface of the glass. Chromoly - see 4130 steel Coppo - This tool is a tapering trough on a handle. It is used to shape wraps into perfect rings. Delrin - Technically this plastic is a homopolymer acetal. It is a hard nylon like plastic used to make mouthpieces. DOM Tube - DOM stand for Drawn Over Mandrel. This is seamless mild steel tube, available in a greater range of sizes than 4130. Jacks - see Borselle Pacioffo - Pronounced (pa-CHO-fo) from a somewhat obscure Italian verb used to describe “feminine fullness”. This tool is basically a jack with wooden blades. It's very useful for opening bowls and working inside vessels when you don't want to leave tool marks. The blades are usually made from a fruitwood, in Italy, often pear. Pinze - Tweezers in Italian. Used to pull out lips, create holes, guide other tools, straighten pieces, shape bits, and about 100 other things. Punty - After a vessel has been inflated on the pipe, the piece is usually transferred to a punty where it is finished. Rigadin - a straight ribbed optic mold. From the Italian noun Riga : straight line Scale - a black flake that appears on the inside of vessels. It comes from inside the pipe, often disloged by steam or agitation. Scale is burned out steel. The most common source of scale is the joint between the head and body of the pipe. Soffietta - Pronounced (sofy-ET-a) from the Italian verb soffiare - to blow. Also known as a puffer it is used to inflate a vessel after it has been transferred to the punty. Tagliante curvo - Translates to curved cutters. Also known as a diamond shear, used to make cuts that come to a point instead of a line as with straight shears. Many uses include guiding punties and bits, shaping glass with the blades, etc. Taglio - Pronounced (talee-O) From the Italian noun tagliare: to cut. This tool looks like a big knife. It's used to shape and cool the glass. Yield strength - The amount of pressure that a material can withstand before deforming. Usually expressed in pounds per square inch (psi). Steel has a yield strength of about 70,000psi, 304 Stainless is about 45,000psi, Chromoly steel is about 100,000psi. The lower the yield strength, the easier it is to bend something. |
