What is the difference between grout and putty? Can I use putty in place of grout for mosaic tiling?

I would like to make my first mosaic table and I'm not sure if grout and putty are the same thing. If their not would putty work?

Definitely don't use putty-not the right product. Use sanded grout for grout joints 1/8' or greater and non-sanded grout for joints 1/8' or less. Sanded grout holds up better than non-sanded (especially outside). Most grouts have additives already in them; just mix with water, per mfr. instructions. Seal the grout with a good penetrating sealer to prolong it's life and appearance.
To install the mosaics use a good multipurpose thinset and be sure it is rated for exterior use if the table will be outside. Some of the cheaper m.p. thinsets are for interior use only. Also, don't do mosaics over particle board.

putty is usually a flexible compound made from gypsum for filling holes and cracks – grout is a cement product with sand added – with mosaic you would want grout or sometimes called mortar to go between the tiles –
in tile work you usually place tiles on a mortar bed and put grout between them after they are set.

You will need to use grout in between the joints

These are NOT interchangeable compounds.
Grout is basically cement and is used between tiles as a permanent part of the tiling job. Putty is a very pliable and temporary medium used in connecting window glass to window frames. If you were to use this on a table, it would be very open to elements that could dissolve and destroy it. Grout, once sealed, is far longer lasting. If the table is used outdoors, it would require latex grout which is used in swimming pools and is suitable for changing weather.
