Footed glass bowl Simon Pearce? - need help please

I picked up this bowl because it felt well made & had what I thought was an unusual pontil? on the bottom. I know it is a longshot but thought someone might recognize it.

It is 4 3/4" to the side edge & is 9 3/4" across the top.



Thank you for any & all advice or opinions!!

 

@i need help - Thanks!!

It does look very similar but it is not signed.

Thanks to @i need help post I edited the title to get some additional input.

 

I have a few of their pieces and they aren't signed but have a sticker.

 

Is the 60 oz. the capacity or the weight?

According to Replacements measurements, this is a Shelburne bowl.

 

The liquid capacity is actually slightly more than 60 ounces but since they are hand blown there is going to be I would think some discrepancies.

According to my scale, the weight is about 35 ounces.

 

I just looked at mine & I do not see any optic effect in my bowl. I do not know how the optic effect is done but could this have been a bowl that for some reason did not achieve the optic effect? This bowl could have been sold as a second & maybe the reason it is not signed.
