I noticed from your descriptions that HCC uses a lot of archival material like acid-free tissue and boxes. May I know where I can purchase these for my own use?
Watercolours, photographs, dyed textiles, paper and coloured surfaces tend to discolour, fade and become structurally weak when exposed to light over a long period of time.
Damage from light exposure is cumulative and irreversible.
All visible light can cause fading and discoloration. However, ultra-violet rays reacting with sensitive components present in pigmented surfaces and dyed materials, cause the most damage.
At the other end of the spectrum, localised heating can cause desiccation, shrinkage and cracking from infrared rays and expansion or contraction due to fluctuating temperature.
