16 jars are exactly twice the number of clay pots made by the craftsman, meaning there are 16/2=<<16/2=8>>8 clay pots
If each jar has 5 marbles, the total number of marbles in the jars is 5*16=<<5*16=80>>80
Each of the clay pots also has 3*5=<<3*5=15>>15 marbles.
The total number of marbles in the 8 clay pots is 15*8=<<15*8=120>>120
There are a total of 120+80=<<120+80=200>>200 marbles.
