Hello everybody

what impressions about this little cup? recent fake?

Hi Giulio, monochrome items are hard to tell because their is no decoration to pin point it to a certain time, to me the foot looks like it could be Ming or early Qing but then the bowl looks perfectly round, can you check for dead bubbles, I have a couple of white monochrome bowl as well one has nice dead bubbles and the other dose not, I know it is still a fairly new science but it is worth mentioning I think.

I started a blog under "dead bubbles" you can search, also Heavenguy has posted about the subject, it was his posting  that I learned and bought a digital microscope online that you can hook up to your computer and get microscopic images on your screen, the one that Heavenguy suggested is a Jiusion 40 to 1000x M.... Digital Microscope, it was under $20.00 a nice little tool it think.
I also bought a Carson Microbrite plus 60x120 for something that you can carry around, dead bubbles are thought to mean that if something has them it would be a minimum of 100 years old to hundreds of years old.

Thanks Stan, I will try the blog

[Hmm]

@stan

Can you just post the website on here, or is it against the rules?  I'm having trouble finding the blog using google.  Thanks.

I found the discussion on dead bubbles here

http://discussion.chinese-antique-porcelain.com/index.php/topic,3395.msg15045.html#msg15045

so the ones I send you in pictures are dead bubbles?

This is either a glaze fault that developed during firing, or it is a spur from stilts being used for firing; depends on the location of it, which it could be. Spur traces are found on glazed bottoms and there are at least three, normally.

Thanks Giulio, for posting the blog, " dead bubbles "  in the photo's you see dark bubbles they are bubbles that have fractures or small openings that allows dirt into the bubble, what you are looking at on the blog is a 40 X 1000 magnification, over long periods of time these bubble darken.

thanks Peter,

It is a spur from stilts used for firing; it's the bottom of a bowl and there are five. I was talking about the bubbles that are seen enlarging the photograph (unfortunately made with an iphone and not very clear)

Thanks Stan,

I understand what you mean by dead bubbles, are those small black bubbles that are seen in the magnification

[peterp]

Now I saw them. This are not dead bubbles. Just normal ones. I would not give bubbles sole importance for dating. They are not a shortcut to identification or dating, not yet. And they will be used with other methods combined, in future.

I agree with Peter 100% but if the dead bubbles are their and everything else lines up, it is a plus, as far as I know the fakers have not been able to duplicate dead bubbles yet.
