Safety precautions applicable to metal working depend on the kind of metal working being attempted. They might include:wear industrial safety glasseswear face shieldwear gloves appropriate to the workguard belts and pinch pointskeep hands and feet out of the working points of machines and tools
you could strengthen it by putting metal bars inside the concrete
The safest way to make a hole in a piece of sheet metal is to use a drill with a metal drill bit or a hole saw, ensuring you wear safety goggles and gloves for protection. Secure the sheet metal firmly on a stable surface or clamp it down to prevent movement. Start with a small pilot hole if necessary, and apply steady, moderate pressure while drilling to avoid slipping. Always be cautious of sharp edges after the hole is made and clean up any metal shavings.
In sand mold casting the molten metal is poured in to the mold cavity , while in pressure die casting the molten metal is forced under high pressure in to the cavity. The sand casting process is used for small batch production where pressure die casting is used for mass production.
i think i could be composition of lead & bismuth.
The handle of a pressure cooker is made from ebonite, a type of hard rubber, because it has excellent insulating properties that prevent heat transfer. Ebonite can withstand high temperatures and does not conduct heat well, ensuring that users can handle the cooker safely without risk of burns. This thermal insulation is crucial in maintaining safety and comfort while cooking under high-pressure conditions, where the surrounding metal can become extremely hot. By using ebonite, manufacturers ensure that the handle remains cool to the touch, enhancing user safety and usability.

It is called a fuse
It may have gotten it too hot and warped the metal rim- or the lid. Check it for true with a straightedge. If the pot or the lid is warped, it's time for a new cooker.
they look like a regular pot but the lid is screwd in tighly and at the top it has a cilindrical metal weight that moves and makes a hizzing sound when the preassure starts scaping trhoug it.
If you plan to cook the artichokes whole, first remove the other leaves, and open the center delicately to remove the choke. Then, put the steamer basket in your pressure cooker (if you don't have one those metal foldable ones that open like flowers will do) add two cups of water with a squirt of lemon. Place the artichokes on the steamer basket inside the pressure cooker face up. Close and lock the top. Turn the flame to high and when it begins to whistle (actually it's more like a hiss) turn the heat down to low and count 10-12 minutes. At which point turn off the heat, release all of the vapor, open the pan and enjoy your artichokes!
A metallic safety shoe is a shoe in which the toes are protected from limited crushing pressure and cutting by a metal guard within the shoe over the toes. This metal guard is called a toe-cap, therefore they are sometimes also referred to as metal toe (safety) shoes. Very often an extra metal plate is put inside the outsole for extra protection against penetration of sharp objects. The toe cap does not need to be made from metal. In addition to steel or aluminum it can also be made from a composite or fiber material. Also the steel midplate doesn't have to be made from metal, making it possible to create a non-metallic safety shoes that provides impact, compression and penetration resistance.

Heavy metal toxicity, could cause glitter like substance to leach out of the skin. Do you cook with aluminum pans or pressure cooker? This is an educated guess. My daughter and grandchild both have this symptom.
If the accessories were designed by the manufacturer of the microwave cooker there will be no problems, no matter what they are made of. Its metal objects that the cooker was not designed for that are problems, especially foil or wire as they are high resistance and can cause fires.
propane is packaged in metal cyliners. These cylinders all meet safety standards and are pressure tested before they are filled for the first time
