Help identifying Porcelain Bowl

Hi, I am new to porcelain, but on my recent trip to Good Will in SC I picked up a beautiful porcelain bowl. I did some research using Google images and read many articles online.
I now believe that my bowl is an Imari style, underglaze porcelain. It is not smooth like normal porcelain, that’s why I believe it’s under-glazed. Only white background feels smooth to touch. It’s 10” wide and 4.5” tall. I also believe that it has a Qianlong red stamp. Design, lines and coloring don't seem mechanical, more like hand painted and not super even. I struggle with identifying the age of the bowl. The stamp doesn’t have a border and is not very bright. The bowl is in great condition, no chips or visible repair. I tried to take best pictures I possibly could, on a rainy day.

Can you give me your thoughts on how old this bowl might be? And why?

Thank you so much,
Liana.

 

Generally speaking, underglaze porcelain is rather smooth to the touch and if held at an angle to the light the surface will seem uniformly reflective. Overglaze decorations often can be felt and when held at an angle to the light the difference in reflective ability is notedly different than the glazed portion because it is applied over the glaze. Many pieces are a combination.

I don't speak or understand Chinese but I "think" this is like your mark though someone else will probably know more. If you scroll down the page to the section titled below, you can see an assortment of similar marks while waiting for a more knowledgeable person.

Qianlong Nian Zhi, Da Qing - Qianlong Period Make, Great Qing Dynasty
These six character marks follow the traditional way of drawing seal marks in archaic seal script, zhuanshu, from the Qianlong period 1736-1795. The manner is a drawing more like an engraving rather than actual hand writing. None of the following marks are of the Qianlong period despite that they say so. See comments next to each individual mark for an approximate date.

Yes this is a modern Chinese bowl in the Imari style.

 

@say_it_slowly is correct. This is the seal form of mark for the Emperor Qianlong, the seal used an ancient form of Chinese script from the BCE period rather than the kanji we see today. It reads Da Qing Qianlong Nianzhi (with an error in Qian, common in reproductions). As this type of Chinese Imari wasn't especially sought after until the later 20th century, this dish is probably fairly recent, late 20th century onwards.

 

Thank you!

 

So is my bowl a combination of overglaze and underglaze?.... and is it hand painted?

 

Just out of curiosity, how much a bowl of this size, condition/quality and date may cost? I bought it for $8.
