Hi Randy, Thanks for this info.
Please answer these questions about nail polish separation and quality:
1. Is a layer of oil/clear substance on top of the pigment (The pigment is still well mixed) a sign that the nail polish is old ? I ask this as I've seen new polishes in the shops with this issue.
2. Also, if you have the above mentioned layer but the pigments have separated, and you have shaken the bottle but this issue reoccurs, is that also a sign of old nail polish ?
3. Quality - when you add thinner too many times, what signs of poor quality should I look out for (I did have a nail polish which even though it had been thinned too many times did not dry properly on my nails - I disposed of that one).
4. Is nail polish chipping after 1 or 2 days also a sign of deteriorating quality ?
Thank you so much for answering these questions - it is very much appreciated.
These are not my pictures but they show similar conditions of some of my nail polish - some of mine still have a good runny texture but darker colour (not clear liquid) at the meniscus. Are those still OK to use or is it best to dispose of them. What would happen if I used them e.g. performance.

Example 2 (all apart from the white one):
Example 3 (the Revlon pink one - except that the colour underneath the darker meniscus is all even and the texture is still runny much like new):

Picture from here is also an accurate representation of some of my collection - even colour throughout but the meniscus is a bit darker.
