Topic: Medley of clear glass bottles - ID on manufacturers & dates sought

[Amaya]

Hi,

I've finally unpacked some more of our inherited glassware & am positively stumped as to their manufacturers, dates,  glass type, usage etc. If anybody out there has the magic answer I'd love to hear from you please.
The hexagonal bottle with the glass screw on lid has no markings. It is 8 cm tall (without the lid), 8.5 cm  with. The widest diameter is 5.5 cm. My friend tells me this was used as a sauce bottle in restaurants in the 60's/70's.  Manufacturer, glass type, date of birth???
'Roger & Gallet  Paris' is embossed on one side of this miniature perfume bottle.  It measures 5.5 cm tall X 24 mm wide X 10 mm deep. Manufacturer, glass type & date of birth???
The small round diamond cut bottle has an opaque diamond shaped plastic stopper. It is 6 cm tall X 4.5 cm at widest diameter. Manufacturer, glass type & date of birth???
Heavy diamond & teardrop clear glass jar with threading at the neck (no lid). Looks like the No. 11 is incised to the base. 9.5 cm tall X 7 cm widest diameter. Manufacturer, glass type, usage & date of birth?
Small clear glass with gorgeous octagonal & diamond cut patterns in square segments, separated by a set of horizontal ridges in two vertical columns to either side. Threading to the neck but no lid. Embossing on base reads '6 BGD' (could be '860'). It is 6 cm tall X 4.5 cm widest diameter. Manufacturer, glass type, usage & date of birth?

Cheers
