Sebring Pottery Co. question

[blws]

I have my grandmother's china and would like to know when it was made.  It was made by Sebring Pottery Co. and it is the China Bouquet pattern.  The information on the back is...  the state of Ohio with the words The Sebring Pottery Co. U.S.A..  To the bottom left is the number 6 and to the right is C-48.  Below is China Bouquet I-K-S518.  Then below that is Warranted 22 K Gold.

I am not as interested in the value as I am in the history.  Any help would be greatly appreciated.
