Enameling involves the firing and melting of suitable glasses onto and into metals for decorative effects. It is done at fairly high temperatures, from 1200F (649C) to a high kiln temperature of 1700F (927C) or so.The primary dangers involve dusts, the particle size of the enamel used, the chemical constituents of the enamel (older enamels frequently contain lead and other toxic metal oxides and chemicals), the infrared radiation of the kiln and sundry opportunities to burn oneself. Enamelists in factories have even been killed by scalds from water when molten enamel was dumped into it.... (1999) Complete Story
Jewelers work with compressed gases of all kinds, in torch systems, kilns, casting machines, abrasive blasters, laser welding machines needing argon and more. Many of these gases are flammable and an explosion hazard, acetylene, propane and hydrogen are examples. Oxygen is often used with these gases. Oxygen is a potent fire risk if it comes in contact with oils, greases or flammable materials, even fingerprint grease left in a fitting has caused a fire before.... (1999) Complete Story
Besides the safety instructions that you get from a tool manufacturer in the tool manual it may be necessary for you to write your own sets of rules up to keep you out of trouble. This is especially important with employees. What follows is an example of thinking about what can go wrong with a tool. The tool used as an example is a mounted grinder. You can do the same sort of rule compilation with all the tools in your shop. See the "General Safety Rules for Tools" article as a starting point, then each tool will have certain idiosyncrasies which need to be noted. Think of it as "What advice would I give to someone to keep them out ot trouble on this machine?".... (1998) Complete Story

It is not wise to share one's living and family space with workshop space. Usually there are chemicals, tools, equipment, processes, sounds, materials, wastes, dusts and so on that are unhealthy to be exposed to that are produced in a work shop.... (2000) Complete Story
Goldsmiths began to use hydraulic presses in small shops in the 1940s in North America. Factories have used hydraulic presses for making blanking out parts and forming pieces for some time, and presses in the 150 to 200 ton range are not unusual in jewelry factories today. These need good machine guarding, maintenance and training for the operators. The smaller shop at the end of the 20th century tends to use slowly operated hydraulic presses in the 12 to 25 ton range for forming operations and some minor blanking, this last often carried out using R.T. or pancake cutting dies. It is the smaller presses I will discuss here...
