What are side effects or risks associated with the use of sun blocks?

Body has natural defense system which protects harmful radiations from penetrating skin. This natural protectant is known as melanin. It increases with the amount of exposure to sunlight and this condition is known as a Suntan. Melanin is to block UV from skin penetration. The photochemical properties of melanin make it an outstanding photo-protectant. Sunscreens are not as efficient as melanin.

Sunscreen ingredients penetrate into the lower surface of skin and increases free radicals which plays a vital role in aging. Prolonged use of sunscreens can cause deficiency of vitamin D3. Deficiency of this vitamin leads bone softening diseases like rickets an osteomalacia. Doctor's advice is to take sun bath without applying sunscreen for 15-20 minutes at least twice a week.

What is the difference between sunscreen and sunblock?

Sunscreen is more transparent than sunblock.

Use the sunscreen of higher SPF value. It protects both from UVA &UVB radiations. The major difference between sunscreen and sunblock is that it breaks down at faster rate and then once the skin is exposed UV rays can penetrate.

You have to apply every 2-3 hours in order to achieve better protection

Sunblock has the same properties it also protects from sun burn by blocking UVA & UVB radiations. Sunblock is not transparent - it is opaque and more viscous then sunscreen. It forms a strong protective layer hence there is no need to apply frequently.

How to Make a Blackboard Paint Surface

Blackboard paint is used to create a writing surface, a conversational piece or a shopping list in your house or school on wood, tile, sheet-rock, glass, metal or on your interior walls. These can be achieved by creating a black, non-reflective, smooth surface that is easy to clean and wipe with a duster or normal soapy water. The surrounding walls are then decorated in more pronounced colors in order to create a contrast.

To make a blackboard, you will need a cleaning cloth, soap, Primer, Paint stirrer and a Paint brush. First clean, dry and rid the surfaces off grease, and other contaminants. If the blackboard paint is to be applied over over a standard emulsion, then you can paint directly on the surface, of course after cleaning off the dirt. However if you are doing it over bare wood, you will need to fill any noticeable cracks and knots with a primer.

During the blackboard paint application, you should stir it while inside the can in order to get a clear and evenly mixed solution. These stirring process should be applied continuously throughout the painting process. Use a brush to apply the first coat, let it dry for some time and then apply the second and third coat, every time sanding it before applying another coat.

Under normal circumstance your blackboard should be ready for use within 24 hours after the last coat. This though depends on the aeration and the temperature of the surrounding. The finished product will give you a Matt black finish, will be hard wearing and non-reflective. The blackboards have found uses on scoreboards and menu boards since they are easy to clean an wipe.

Are you a taster or a stirrer?

If it is a dish I am well versed in cooking I stir. If not, or if I am of lesser skill than the stirrer, I bask in the pleasure of being the taster.
