How do I identify an 18th century glass bottle?

Examine the base for a rough pontil mark where the blowing iron was snapped off, indicating hand-blown manufacture before modern mould techniques. Look also for deep metal weight, dark green or clear metal tones, and wear patterns appropriate to age. Check the neck construction, as many Georgian forms feature distinct applied glass rings or heavy kick-up bases designed to settle sediment in wine vessels.

Were these bottles used for wine storage?

Most surviving heavy glass bottles and shoulder decanters served as service vessels at the dining table rather than long-term cellar storage. Wealthy households transferred wine from wooden casks into these decorative containers for immediate pouring. Smaller flasks and scent bottles carried personal spirits, perfumes, or medicines, while fitted campaign sets allowed officers to transport liquids securely during travel.

What is the difference between a decanter and a serving bottle?

Decanters generally feature distinct stoppers, specific shoulder profiles, and cut or engraved labels identifying contents like Madeira or port. They were engineered for stable pouring and aeration at the table. Serving bottles often retain simpler cylindrical or mallet shapes with less formal neck rings, serving as general utility containers for daily schnapps, beer, or local wines across European households.
