Efflorescence can often be removed from concrete using phosphoric acid. After application the acid dilution is neutralised with mild diluted detergent, and then well rinsed with water. However, if the source of the water penetration is not addressed efflorescence may reappear.
Glycol and boron solutions are hydrophilic (water-loving) and react with the water in wood, making it unavailable for the fungus. This is why dry rot can seem to be a little stringy; cells grown in drier periods are smaller than the larger, "plumper" cells that grow in Spring, as can be seen in tree rings used to tell how old the tree is. This ...
Glass disease, also referred to as sick glass or glass illness, is a degradation process of glass that can result in weeping, crizzling, spalling, cracking and fragmentation. [ 1 ] [ 2 ] Glass disease is caused by an inherent instability in the chemical composition of the original glass formula. [ 3 ]
Step Three: Remove Streaks. Combine one part vinegar and one part water in a bowl. Dampen a clean microfiber cloth with the mixture and apply it to the glass, wiping it down well for a streak-free ...
An affected gastropod shell (a juvenile Agathistoma) from a museum collection. Byne's disease, more accurately known as Bynesian decay, is a peculiar and permanently damaging condition resulting from an ongoing chemical reaction which often attacks mollusk shells and other calcareous specimens that are in storage or on display for long periods of time.
For example, cracks can form in a gesso ground due to the embrittlement and movement of its support, then become visible in the paint film. [22] Tempera can develop cracks over time that are visible to the naked eye, and flaking caused by air bubbles. Tempera paintings are thought to be more resistant to materials typically used during cleanings.
Glasswork and cerarnics: antireflection treatment of optical glass; application of light-diffusing coat to electric light bulbs; binding agent for ceramic mixtures, resistant to strongly corrosive mediums, with high manufacture of fireproof material standing temperatures of about 1750 °C and stress of above 127 kg/cm3;
But the hole was too small for the octopus to grab onto and remove the fish to eat it. The bottle could be opened with its screw top. Scientists wanted to see if the octopus could find a way to ...
