  • Mold Making for Glass Art
    Mold Making for Glass Art a tutorial by Dan Jenkins When Dan Jenkins retired he did not originally intend to make tools and molds for glass artists. However, his wife and friends who work in fused glass were constantly calling on the skills he developed during 30 years as a marine engineer in the Canada Navy to produce items that were needed but unavailable. He began his career on steam driven ships for which it was impossible to get parts. The engineers had to fabricate their own parts out of whatever was available to them. Dan has drawn on his knowledge of woodworking, metalworking, design, engineering and making something out of nothing. He discovered that he enjoys the challenge of designing new tools that are practical economical, and easy to use. Dan has always enjoyed teaching and spent much of his time in the navy as an instructor both at sea and onshore. Dan currently lives in Victoria B.C. with his wife, two cats, and 3 dogs. Mold Making For Glass Art by Dan Jenkins Choosing a Prototype The first projects you wish to tackle should be fairly simple because failure the first few times is Making molds for your own use or for not only possible it is probably inevitable. The reproduction is fairly easy to do and very first objects I tried to cast were self-produced satisfying. Making your own molds frees you wood blocks in the form of squares and from relying on molds made by others and triangles, simple shapes which should have allows you to tailor your mold for your own taste.

  • Fabrication of Ceramic Moulds Using Recycled Shell Powder and Sand with Geopolymer Technology in Investment Casting
    applied sciences Article Fabrication of Ceramic Moulds Using Recycled Shell Powder and Sand with Geopolymer Technology in Investment Casting Wei-Hao Lee, Yi-Fong Wu, Yung-Chin Ding and Ta-Wui Cheng * Institute of Mineral Resources Engineering, National Taipei University of Technology, Taipei 10608, Taiwan; [email protected] (W.-H.L.); [email protected] (Y.-F.W.); [email protected] (Y.-C.D.) * Correspondence: [email protected] Received: 1 June 2020; Accepted: 29 June 2020; Published: 1 July 2020 Abstract: Lost-wax casting, also called precision casting, is the process of casting a duplicate metal sculpture cast an original sculpture. The ceramic shell mould used in lost-wax casting usually consists of several layers formed with fine zircon and granular mullite particles using silica gel as a binder. However, it is a complicated and time-consuming process. Large amounts of waste moulds that need to be disposed and recycled become an environmental concern. In this study, waste shell sand from the recycled mould and calcium carbonate/metakaolin were used as raw materials to prepare geopolymer slurry and coating. The influence of mixing ratio and the SiO2/K2O modulus of the alkali solution on the setting time and green/fired strength were evaluated. Ceramic shells with one to four layers of geopolymer slurry and waste sand sprinkling were fabricated and tested for their permeability and green/fired strength. It was found that geopolymer shells had higher green/fired strength and better permeability than the original zircon/mullite shell. For foundry practice, metal casts were fabricated using recycled ceramic shell moulds with one to four layers of geopolymer coating.

  • DROSS in DUCTILE IRON by Hans Roedter, Sorelmetal Technical Services
    98 DROSS IN DUCTILE IRON by Hans Roedter, Sorelmetal Technical Services WHAT IS “DROSS ”? magnesium with other elements. Dross also Dross is a reaction product which is formed from occurs in the form of long stringers instead of Mg treatment and during subsequent reoxidation concentrated “slag like” areas. When it occurs in of Mg rejected from the molten metal before it this string like form it acts like cracks or flake solidifies. It is therefore just another word for a graphite in the structure and so fatigue strength specific type of slag (reaction product). and impact strength of the material are lowered considerably. The reaction binds magnesium with sulphur, oxygen and silicon and forms continuously. This “dross” is light weight and so it will generally be found in the upper surfaces and under cores, but it can be entrained throughout the metal as well, especially with colder pouring tempera - tures. It is very difficult to completely avoid the reaction of magnesium with these other elements, since we need magnesium to form nodules. We are always confronted with the problem of dross in the production of Ductile Iron. WHAT IS PROMOTING “DROSS ” AND WHAT CAN BE DONE TO KEEP THE “DROSS ” OUT OF THE CASTING ? Since “dross” is always connected with magnesium, it is necessary to keep the magnesium level as low as possible. Good inoculation practice with some late inoculation in conjunction with sufficient magnesium will When looking at “dross” in the microscope you produce nice round small nodules. See will almost always find flake graphite in Suggestion Sheet 76.

  • St Luke's Farnworth BELL CASTING
    St Luke’s Farnworth BELL CASTING by Geoffrey Poole In the earliest days they were cast in different sizes to produce different notes but no attempt was made to tune bells until the 16th Century with the advent of change ringing. In those times bells were roughly tuned – where the inside of the bell or the edge of the lip was chipped away with a hammer and chisel – eight bells could be tuned to an octave of eight notes. Some deprived communities used a hagiosideron, a shaped piece of metal which was struck in a similar way to a bell. Also again due to lack of money bellcotes were used instead of costly towers. A bell-cot, bell-cote or bellcote is a small framework and shelter for one or more bells. Bellcotes are most common in church architecture but are also seen on institutions such as schools. The bellcote may be carried on brackets projecting from a wall or built on the roof of chapels or churches that have no towers. The bellcote often holds the Sanctus bell that is rung at the consecration of the Eucharist. Bellcote is a compound noun of the words bell and cot or cote. Bell is self-explanatory. The word cot or cote is Old English, from the Germanic. It means a shelter of some kind, especially for birds or animals (see dovecote), a shed, or stall. Examples of bellcotes In order St Luke’s Farnworth Bell-cot at St Edmund's Church, Church Road, Wootton, Isle of Wight, England Church of England parish church of St Alban the Martyr, CharlesStreet, Oxford.

  • 6 Simple Steps to Becoming a Lost Wax Casting Pro,The Evolution Of
    6 Simple Steps to Becoming a Lost Wax Casting Pro Lost wax casting blends old and new in truly remarkable fashion. Our industry is constantly changing, adapting ancient techniques to modern technology. So, we’ve asked our experts to walk us through lost wax casting: STEP 1 – PATTERN Wax patterns are made by one of the following ways: carving, build-up, hand forming, or mold reproduction. STEP 2 – SPRUING OR SETTING UP Spruing is the leading cause of shrinkage porosity, or the pits you see during polishing. Fix this by ensuring the following: • The sprue should be thicker than the heaviest part of the pattern. • It should also be attached to the heaviest part of the pattern as well. • The sprue should be no longer than is absolutely necessary. These are much more effective than looking for that optimum (magical) cast temp. STEP 3 – INVESTING Investing is more chemistry than craft. Measure your powder and water and follow your supplier’s instructions for mixing, curing, and burnout. Keep this in mind: your casting surface is only as good as your wax and investing procedures. • Weigh investment material and measure water according to manufacturer’s recommendation. • Fill flask containing wax pattern and either vacuum or vibrate to remove air from the slurry. • Allow invested mold to air-dry for two hours or more before starting the burnout. STEP 4 – BURNOUT • Place invested flask in furnace preheated to 300ºF. Hold at this temperature for one hour or until the wax has drained. • Raise temperature at the rate of 300º/400ºF per hour until temperature of 1350ºF is reached.
