How can I see how old my Bing & Grondahl porcelain is?

The Trademark/Factory Stamp

It is the factory stamp or trademark of Bing & Grondahl, the Danish porcelain manufacturer, that helps determine the age of any porcelain item made by B&G.

The porcelain factory Bing & Grondahl was established 19th April 1853 by Vilhelm Grondahl and the brothers Meyer and Jacob Herman Bing, who where book and art dealers.


About the Bing & Grondahl Trademark

In 1898 Bing & Grondahl chose "The Three Towers" as their trademark. "The Three Towers" is an ancient symbol of Copenhagen originating from the castle of Absalon and the same symbol used in the City Arms of Copenhagen (bishop Absalon founded Copenhagen in 1167). The trademark was used with little variations but with different writings until 1970. Afterwards their expression became more stylized with less ornamentation.

Many beautiful old porcelain figurines, coffee and dinner sets, plates, bells, Christmas drops and much more have been produced by Bing & Grondahl through its many years of activity.

By looking at the trademark or factory stamp under an item you can actually see how old the porcelain is.

Delivery terms

There are 2 types of delivery terms:

  1. Delivery of items in stock
  2. Delivery of customised/special ordered items and items not in stock

Delivery of items in stock

All items currently in stock are items that we currently have stored at our warehouse.

Items in stock are normally shipped immediately (within 1-4 business days). When your payment has been confirmed by us, you will receive an order confirmation.

Should the time of delivery be delayed beyond normal (i.e. orders of large quantity) we will let you know.

Attention! By delivery time we mean the time from the order is confirmed to the order is shipped from DPH Trading. Not the time between the order is made to the time you receive the order.

Delivery of customised/special ordered items and items not in stock

Customised/special ordered items and items not in stock are all items we do not currently store at our warehouse.

We are therefore depending of the various suppliers, dealers and collectors and the time of delivery is only an estimate.

In some situations it can be impossible for DPH Trading to predict the exact time of delivery if the items are specially ordered or customised.

Sometimes the items have to be produced from scratch. If the particular item is of significant age we may have to rely on private collectors who are willing to sell.

All the customised/special ordered items are delivered as close to the agreed delivery date as possible.

DPH Trading could take precautions for the delivery of entire or parts of an order. Part deliveries can occur. We always strive to inform you as quickly and efficiently as possible, should any deliveries change or be divided into separate deliveries.

In extraordinary situations negotiations can be made where the buyer are not responsible for the extra delivery cost in case of part deliveries.
