Stainless steel used to make objects previously made of lead
Nickel Magazine, November 2005 -- They are made of S30400 stainless steel. The pins are 1.6 centimetres (cm) long and 0.74 millimetre (mm) in diameter and are spot-welded to a stainless steel base 3 mm thick. Two different base diameters are pictured at left: 2.2 and 2.9 cm.
They have been manufactured to replace units that were previously made of a lead base.
The correct answer is: These stainless steel objects are called pinfrogs. They are placed in the water at the
bottom of a flower vase and the end of the stems of flowers are pushed onto the pins. The weight of
the pinfrog keeps the flowers from floating and helps to maintain the flower arrangement.
Many thanks to those readers who sent answers to this quiz. We will forward your e-mails to the
manufacturer (see contact informtion below) who will send you a sample if you wish.
