Can someone help me identify this company on Tureen bowl?

I can't find anything about Ionia Mfg Co other than them producing automotive stuff.
Then the stamp over on the bottom has me confused.

 

I don’t think the first letter is an I. Also might be missing letter(s) before it.
Also not sure last letter is A.

 

I think the circle stamp underneath simply says "Semi Porcelain"
Over stamped with ??sonia MFG. Co Trenton NJ

There were a lot of pottery companies in Trenton. I didn't see this mark, but I could have missed it.

Hi,
I love the violets on your piece. I am getting an Ansonia vibe on your piece. Lots of potteries in Trenton at that time.

Interesting......thank you!

 

I'm wondering why they stamped over another?

 

Thanks! I know, I saw it in the thrift store and just had to have it!

 

I could be wrong, but wouldn't a tureen have a ladle and a notch in the lid? You don't give measurements but I wonder if it's just a covered serving bowl like fror vegetables?

Sweet violets

 

The two stamps probably mean that the blank came from one company, and a second company decorated it. That's generally the case when the marks are in competition, when one is overriding the other. If they were separated, possibly manufacturer and retailer.

 

Here's a blow-up if it helps any.....I picked up the 'porcelain' but hadn't gotten the 'semi'.....and yes, I love the violets too!!!!! Does it also say W M Co. ???

@VickyRenee, Lookee what came up when I put those initials in!!!!! I don't see yours EXACTLY, but it shows who the maker is!!

Just wanted to say...it is a nice bowl! Yes--probably vegetable serving piece...Love the violets !

 

Yes, lovely bowl .. I would have jumped on that too, nice find ... Joy.

 

Oh that's awesome! Yes! I see it now!
Thank you!

 

I'm not sure really LOL I had to google vintage serving bowls just to find out if it had a name for this kind of bowl.

It reminds me of a gravy bowl/vegetable bowl LOL! I didn't know the word Tureen existed until I got this bowl!

 

Thank you very much!!

 

Thank you! I looked and you're right nothing like mine! I'm going to keep looking though, appreciate the site info!

 

Oh and it's between 3 1/2"- 4" tall (w/o lid)
12" across from handle to handle.

 

Nice Going, Aquitaine!

 

So now I'm wondering what the top stamp actually says LOL!

 

I think @gregsglass is likely to be on the right track, that it's Ansonia Mfg Co. Or at least, that's what I think he meant!
