P-TEA Stock solution (Gainer)

TEA ------------------------ 100 ml
Pyrogallol ----------------- 7 grams

Dilute 1 + 50 (with water) for use

I haven't done enough testing with P-TEA to recommend times and temperatures. Hopefully, either Jay or Pat Gainer will respond.

A developing time guess for TMY is 10 min at 70 F with 10 sconds of agitation per minute.

A 0.1% sodium sulfite solution can be used (instead of water) to prepare the developer if you want a non-staining result.
