Mold and Mildew

These are types of fungi; typically, mold is black or green, and mildew is gray or white. Mold tends to grows on food, whereas mildew grows on damp surfaces, like bathroom walls, basement walls, or fabrics.

Mold grows in the form of multicellular filaments or hyphae, while mildew has flat growth. Mildew is often referred to as a kind of mold and is classified as powdery (under the order Erysiphales) and downy (under the family Peronosporaceae).
Mildew is a specific kind of mold, usually with a flat growth habit. Mold is a fungi that contains multiple identical nuclei. It grows in the form of hyphae of filaments.
Mildew could be downy or powdery: Downy mildew starts as yellow spots that first become brighter in appearance and then the color changes to brown. Powdery mildew is whitish in color and that slowly turn yellowish brown and then black. Mold has a fuzzy appearance and can be an orange, green, black, brown, pink or purple in color and can be found in several shapes.
Some molds are used in food production, for example, Penicillium is used in the production of cheese, Neurospora in the production of oncom, which is made from the by-product of tofu.
To prevent mildew at home, keep all the areas moisture-free. There are mildew removers available at stores to eliminate mildew. To protect crops from mildew use mildew-resistant seeds, remove infested plants, avoid overhead heating.     To prevent mold in your home, you need to keep all the areas dry and moisture-free.
Prolonged exposure to mold spores can cause health problems such as allergic reactions and respiratory problems, due to the toxins (mycotoxins) it produces.

Mildew can cause damage to crops and other plants it infests. Inhalation of mildew can cause coughing, headache, scratchy throat and lung problems. Mildew can also start growing in lungs and cause other serious health problems.

Some molds are used in food production, in the production of bread, soya sauce and so on. Mildew has no uses as such in food production.

Casting, Dies, and Molds

Casting is a manufacturing process in which a molten metal is injected or poured into a mold to form an object of the desired shape.

Molds tend to be used to produce products that need to be hollow in the middle, whereas dies are used to stamp solid products out of media such as steel.

A die is a block of metal with a special shape or with a pattern cut into it that is used for shaping other pieces of metal such as coins or for making patterns.

Tool and die makers are a class of machinists in the manufacturing industries that make jigs, fixtures, dies, molds, machine tools, cutting tools, gauges, and other tools used in manufacturing processes.

Six Uses for Butter

Butter isn't just good for topping toast and popcorn. There are plenty of other things it is useful for, such as:

Swallowing pills: Coat the pills with a thin layer of butter to make them go down easier, especially bigger pills and ones that have no coating.

De-stress cats: If you're moving or throwing a party, your cat can get a bit stressed by the sudden change in the environment. Put a little dab of butter on the top of her paws. She'll be distracted by cleaning herself.

Prevent cheese mold: Put a thin coat of butter on the cheese after you cut it so it won't get too hard or start molding, especially harder cheeses.

Preserve onions: If you cut an onion in half and decide to leave the other half in the fridge, coat the exposed side with a bit of butter to keep it fresh longer.
