There have been a few of these, although I'm not sure they're all available on iPlayer:
The two you watched were from the first outing of the series
Handmade by royal appointment included John Lobb shoes, the Silversmith Simon Benney, Steinway and Wedgewood.
...On the silk road showed traditional wood carving and pottery and weaving/dyeing families.
...Japan covered swordsmiths potters and kimono makers.
For those interested in arts and crafts they're really good TV, far better than the pretend competition pottery/baking/sewing tosh that infests most channels.
