It will float.
If it is placed at depth in the glycerin, it will move upwards, accelerating until it reaches terminal velocity, the same as it would move downwards if the density were greater than that of the glycerin. The force on the ball is equal to the weight of the ball minus the weight of glycerin displaced by the ball (i.e. the weight of a ball’s volume of glycerin), and can be positive or negative, or zero if they are equal.
