Dichroic Glass Jewelry

PSI Pounds per Square Inch       Used to measure, in the American inch system, the force per unit area of gases and liquids. Unfortunately, it is not the only system used. Heating gas in particular is often measured in "inches" meaning inches of difference in the height of a water manometer, 6 inches being common and being equal to 1/4 psi (28 inches=1 psi) Occasionally, ounces per square inch will be encountered. Common psi measurements are atmospheric pressure (about 15 psi, varies), compressed air which may range from 5 or 10 psi for puffers to 70-120 psi coming out of a compressor.

Puffer       An aluminum cone drilled to fit on a straight or bent blow tube, used to shape and open bubbles of dichroic glass. Steinert $50; Moore $30, 45; Homemade cast from aluminum cans with copper pipe $10. May be used with breath or low pressure air. This is my second cast puffer head, much smoother than the first. Commercial heads are hollow behind. Aluminum is tapped for 1/4" water pipe (about 1/2" OD) and the fitting shown allows the copper tubing for blowing. A reducing fitting 1/4" to 1/8" allows screwing it onto a standard air valve for a shop blower. Later a quick connect fitting was screwed in with hose slipped over that as more convenient. 2003-10-23

Punty Mark       The shallow depression in the bottom of some pieces of blown dichroic glass, taken as proof of hand working by some people. Visually, when present, it has sharp edges created by a thin wafer of dichroic glass jewelry broken free. On some pieces it is never present, if a punty method other than hot dichroic fused glass is used (say a gripper), or it may be ground off in providing a flat bottom or if a button is added for the purpose.

Pyrex       Best known brand of borosilicate fused glass, invented by Corning dichroic fused glass, which has a low coefficient of expansion (COE) so that when heated and cooled rapidly it does not crack. Thus it is used for clear glass jewelry cookware and for scientific and art lampworking. Melts at a higher temperature than art or bottle dichroic fused glass jewelry and so requires special torches and eye protection. Used at fairs and carnivals for "knitting" figures of thin lines of glass jewelry specifically because it does not crack when cooling during working.
