There are many glass items which belong in the properly-equipped kitchen, and they form a fascinating range of talking points in our period interior. We believe that we have completed our catalogue of Dutch pudding forms ( or jelly-moulds) and are currently investigating other areas of kitchenalia to find out what belongs in our farmhouse cupboards. There is a wider range of glass items which are made for use in the kitchen, of course. Modern ovenproof glass must contain the mineral borax, and, since this raw material can only be sourced from the west coast of the USA, it has never been economic to produce modern (i.e. ovenproof/heat-resistant) kitchen glassware in The Netherlands. The arrival of Pyrex brought with it 'oven-to-table' ware, and therefore also meant the end for the 'nest of bowls' which had previously been at the centre of the dutch table setting. Here is some of the pressed glass items which we are trying to identify:

Citrus Juicer The basic design of a 'lemon squeezer' hasn't changed much in a hundred years, and you can still buy similar items today. Among the more collectable features of early juicers are those made in uranium green ('anna groen'). It is likely that the basic model has been coninuously evolved since the earliest days of factory glass. Some forms of orange juicer have been found with a high foot rim and a deep trough to collect the juice, but the traditional lemon squeezer (with a reservoir sufficient for the juice of 2/3 lemons), is much more common. There is no reference to them in the literature, and so the exact catalogue numbers and dates remain unclear.
Rasps and graters The modern kitchen has grown accustomed to graters with metal blades, but there are some special properties of glass which can be used to get a range of effects.The large rasp on the right is 'Frieda' from the Walther factory in Dresden
Fridge Boxes There are thought to be several similar sets of fridge boxes which were produced by the Dutch factories, however they are barely marked, and extremely similar in most details. The first design of pressed glass fridge boxes is Kubus by the German designer W. Wagenfeld in 1938. Storage/Pickling Jars Leerdam's storage jars often bear the factory logo. Normally they would be fitted with rubber sealing rings between the jar and the lid.
