Tips (Jewelers Bench)
| Shakudo Alloy |
Copper - 94-96%
Gold - 4-5%
Silver - 1.5% or less |
| Compounds & Effects - Hydrochloric Acid |
| An irritant to the respiratory system and corrosive to the skin. |
| Compounds & Effects - Cadmium |
| Constituent in some solder and brazing materials. Fumes can cause severe lung irritation and fatal pulmonary edema. Can also result in kidney damage, anemia, and damage to teeth, bones, and liver. May also cause lung and prostate cancer. |
| Compounds & Effects - Benzene |
| Skin contact, ingestion, and inhalation can result in cumulative poisoning. May destroy bone marrow causing anemia and leukemia. Highly flammable. |
| 18K White Gold Alloy |
75% fine gold
25% palladium |
| Compounds & Effects - Nickel |
| Fumes of nickel may cause skin allergies and eye irritation. Chronic inhalation of fumes may cause lung or nasal cancer or irritation of the upper respiratory tract. Oxy-Acetylene welding with nickel can result in the formation of toxic nickel carbonyl gas that might cause pulmonary edema. |
| 18K Yellow Gold Alloy |
75% fine gold
12.5% fine silver
12.5% copper |
| Compounds & Effects - Liver and Sulphur / Potassium Sulphide |
| Will create highly toxic fumes of oxides of sulfur when heated to decomposition. Can cause damage to the eyes and lungs. |
| Compounds & Effects - Styrofoam |
| Sometimes used for casting models. Releases toxic gases when heated or burned. |
| Compounds & Effects |
| Toxic by skin contact and may cause skin cancer. Avoid inhalation and ingestion. |
| Compounds & Effects - Coal |
| Dust is toxic if inhaled. Can cause black lung or a disease similar to silicosis. Toxic fumes or ash may be released upon burning. |
| Compounds & Effects - Tin |
| Inorganic tin compounds can be fatal if ingested. Vapors and fumes are toxic. |
| Compounds & Effects - Acetylene |
| High concentrations of acetylene and carbon dioxide become asphyxiating by preventing normal supply of oxygen to the lungs. Acetylene also contains toxic impurities. Highly flammable and explosive. |
| Etching non ferrous metals |
| This [etching metals] is usually a dangerous and toxic task, but it can be made safer and easier. You can use a Sharpie waterproof marker as an acid block and ferric chloride (available at Radio Shack - it is also used to etch circuit boards and other materials). Draw on the metal with the Sharpie where you don?t want the metal eaten away, or color the whole piece and use a scribe to draw in your design. |
| Compounds & Effects - Copper |
| Skin contact can cause allergies in some people. Inhalation of copper oxide fumes may cause irritation to the lungs and intestines. |
