A game of charades

Question

Here are ten cryptic clues in the "charade" style, meaning that that's the only wordplay involved. That's a big hint for a cryptic clue! — so I'm not giving you letter counts.

• Second-rate wafer material is bitter
• Hurry up! Leave us, heretic
• Top student from a southern port
• Glass engraving is offensive
• Duke's state: sober
• Check flower for return to life
• Cleveland site was erected near jelly, perhaps
• "Facial hair is a necessity" —a Fidel supporter
• Belted girls to obtain a form of protection
• Nixon and Carter backer

(These don't combine into one master puzzle or anything like that. They're just ten separate clues. Oh, and I'll provide letter counts if needed after a time.)

---

Hint added later: The respective letter counts (in order) are

6; 7; 10; 9; 9; 13; 9,7; 8; 10; and 6.

Hint added even later:

"Top" is perhaps slightly unfair. Better would be "Max, a student from a southern port".

Hint added even later: The respective first letters of the answers (in order) are

B, R, C, P, L, R, R, M, S, and P.

Hint added even later: The respective definition halves of the clues are at (in order) their

end, end, end, end, start, end, start, start, end, and end.

Hint added even later: Only three clues remain unsolved. Hints for them are:

Second-rate wafer material is bitter: The attempted answer had the right sense of "bitter".

Top student from a southern port: The definition half is "from a southern port".

Cleveland site was erected near jelly, perhaps: Not Ohio.

Answer 1

A quick perusal over morning coffee can provide one small contribution:

Check flower for return to life - REINCARNATION [REIN + CARNATION]
"Facial hair is a necessity" —a Fidel supporter - MUSTACHE [MUST + A + CHE]

And a couple more over dinner

Belted girls to obtain a form of protection - SUNGLASSES [SUNG + LASSES]
Nixon and Carter backer - PATRON [PAT + RON]. How long did I spend trying combinations of Richard and Jimmy!?

Looks like I'm needing those clues, but another one solved over morning coffee

Hurry up! Leave us, heretic - RUSHDIE [RUSH + DIE]

Starting to be a little less confident now.....

Duke's state: sober - LANDGRAVE [LAND + GRAVE]

And now clutching at straws I think, unless more clues are on the horizon......

Glass engraving is offensive - PHILIPPIC [PHILIP + PIC?] not sure how pic fits in here
Second-rate wafer material is bitter - BRUMAL [B + RUMAL?] not sure how wafer would fit in here
