page-settings How much Slug detail to use in store and pages

Site URL: http://sandersraku.com

SEO Question re how much detail to include in slugs in store and in descriptive pages:

• I'm in process of creating a SHOP to sell Raku pottery at Sandersraku.com - not public yet. The shop is organized around styles/forms, so , for example, an item may reside at: https://www.sandersraku.com/shop/saggar/bowls, where saggar is the style and bowls is the form. Fyi, there are six total categories and each may have as many as 6 forms, i.e., bowls, platters, vessels, etc.
• If you know pottery, you know that Raku is a form/method of producing pottery.
• This site sells only raku, so "raku" or "raku pottery" are likely search terms.
• Note that the current domain contains the word "raku": Sandersraku.com. (SteveSandersRaku.com, will be installed later)

My SEO question concerns the store and corresponding descriptive page slugs and resulting URLs:

Currently, for one form, for example,  the shop and page URLS are:

• Shop: https://www.sandersraku.com/shop/saggar/bowls
• Descriptive Page: https://www.sandersraku.com/sagger-raku

Should I change the form to:

• Shop: https://www.sandersraku.com/shop/raku/saggar/bowls  
• Page:  https://www.sandersraku.com/raku-saggar 

OR, should I elaborate the "raku" slug to "raku-pottery"

• Shop: https://www.sandersraku.com/shop/raku-pottery/saggar/bowls, and
• Page: https://www.sandersraku.com/raku-pottery/saggar

Bottomline question: should I use the slug /raku/ or /raku pottery/ to improve indexing and make the site be more likely to be found when user searches for  "raku" or "raku pottery"?

Thanks ahead for your expert advice.
