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. -
Making a Skull Ring
Making a skull ring The first people to utilize the lost wax process is unknown as it is shrouded in history. It is well documented that it has been used for thousands of years to produce objects in metal which could not be produced any other way, due to the complexity of their design. The lost wax process allows anything that can be modeled in wax to be accurately transmuted into metal. Most fine jewelry made from gold and sterling are made using lost wax casting as it produces the highest detail The Wax Models are placed in a Plaster Mixture which then aloud to harden. Once the plaster mixture (investment) has set hard, the flasks are placed in a kiln, slowly heated to between 1000 and 1250 degrees F, and held at that temperature until all wax residues have disappeared. The place where the wax was is now a void, hence the "lost wax" designation for this process. The metal is then melted in a metal furnace and the molds are filled with liquid silver by hand while the mold is still very hot. The flask is then allowed to cool and the investment mold is broken away revealing the metal piece. This process faithfully reproduces every detail of the original wax as well as the gates and vents, which must latter be cut off with a jeweler's saw. http://davescustomskulls.com/MAKING_OF_A_SKULL_RING.html (1 of 7) [10/27/2007 8:07:45 AM] Making a skull ring After cutting away the Silver Tail-(Sprue) the Hand Finishing Process begins with the Many different Steps shown below to BRING final Details and a Mirror Finish to the RING surface. -
The Diamond Glass Companies of Montreal, Canada
The Diamond Glass Companies of Montreal, Canada Bill Lockhart, Beau Schriever, Bill Lindsey, and Carol Serr The Diamond Glass Co. and Diamond Flint Glass Co. were two in a series of Canadian companies (headquartered in Montreal) that began with the Excelsior Glass Co. in 1879 and culminated as Domglas in the 1990s. This chapter deals with the first four firms during the 1879-1913 period (see the Dominion Glass section for the later companies). None of the glass houses used manufacturer’s marks on bottles, but all of them left embossed jars that can be traced to them. The Diamond Flint Glass Co. also made – and marked – insulators. Histories Excelsior Glass Co., St. Johns and Montreal, Quebec (1879-1883) William and David Yuile acquired control of the bankrupt St. Johns Glass Co. at St. Johns, Quebec, in 1878. They renovated the factory and incorporated in April of the following year as the Excelsior Glass Co. The plant made fruit jars, a general line of bottles, and insulators. Unhappy with the location, the brothers moved the factory to Parthenais St., Montreal, in 1880. The new plant produced prescription ware, fruit jars, and some tableware. The firm reorganized in 1883 as the North American Glass Co. (King 1987:67-70). Figure 1 – Beaver Goblet (Sean George Pressed Glass & Goblets) Toulouse (1971:189) told a slightly different story. He claimed that the Yuile brothers “had taken over the Foster Bros. Glass Co. Shortly after it was founded.” They renamed the plant the St. Johns Glass Figure 2 – Beaver band Co. in 1875 and the Excelsior Glass Co. -

Investment Casting Or the Lost Wax Process
Investment Casting or The Lost Wax Process Apecs Investment Castings was founded in 1963 and is now situated in the Melbourne suburb of Burwood where we have been since we outgrew our Canterbury factory in August 1987. The company name (APECS), stands for Anthony Philip Eccles Casting Service. Investment is a type of plaster that we use in our process of reproducing multiple copies of an original master pattern which is usually supplied to us by our customers. This is a classic 18ct yellow gold emerald and diamond ring taken from the Apecs catalogue. The next series of photos will show the steps involved in producing multiple copies of this ring. An original master pattern is designed and fabricated by our customers and supplied to us to reproduce in the quantities and metals of their choice. It is important to ensure that the master is made as accurately as possible and to pay particular attention to the finish of the master pattern. The better the quality of the master pattern the better the casting result. The finished master pattern ready for the caster. A picture of the master pattern is drawn and a mould number is allocated for identification. When the customer wants to reorder he quotes the mould number for the pattern he wants. A sprue is soldered onto the pattern. This sprue enables the pattern to be easily located in the mould and will provide the path for the wax to be injected into the rubber mould. To make a mould the master pattern is placed between sheets of uncured vulcanising rubber. -

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. -
The Lost-Wax Casting Process—Down to Basics by Eddie Bell, Founder, Santa Fe Symposium
The Lost-Wax Casting Process—Down To Basics By Eddie Bell, Founder, Santa Fe Symposium. Lost-wax casting is a ancient technique that is used today in essentially the same manner as it was first used more than 5,000 years ago. As they say, there's no messing with success. Today, of course, technology has vastly expanded the technique and produced powerful equipment that makes the process faster, easier and more productive than ever, but the basic steps remain the same. The steps below represent a simple overview and are intended to provide a beginning understanding of the casting process. Concept This is obviously where the design is initally conceived, discussed,evolved, and captured on paper—or on computer; CAD (computer aided design) software is increasingly popular among designers. You create the design you envision using the computer tool and the software creates a file that can be uploaded into a CNC mill or 3D printer. Model Build a model, either by hand-carving, guided by the paper rendering, or by uploading the CAD file into a computer controlled milling machine or a 3D printing machine. Models are made using carving wax, resin or similar material. This process can also be done in metal by a goldsmith or silversmith. Note: If a 3D printer or other rapid prototyping equipment is used, it is possible to skip the molding and wax-injection steps by using one of the resins that are specially made to go directly to the treeing process. Molding Create a mold from your master model, placing it in one of a variety of rubber or silicone materials, curing the material, then removing the model from the finished mold. -
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. -
