I believe your bowls are fairly modern. They are like Imperial Candlewick, but I'm pretty sure that Imperial did not make jadeite candlewick glass.
There is a very good person (Fran) for questions about Candlewick items (and items that look like Candlewick). If you post this on the eBay
Pottery, Glass and Porcelain discussion board and include the words
glass and
Candlewick? (with the question mark) in the post title, I'm pretty sure Fran will tell you who might have made your square bowls.

Agree..fairly new. 
I agree Wilson. I have always loved Jadite (although I sold my extensive collection back in the 80's). I considered starting to collect it again but the resurgence of reproduction jadite during the 90's just turned me off completely. Everyone starting with Martha (Yes, it was her fault 
) to Target was selling this stuff. I find loads of it when antiquing and cruising on ebay.
