Corking tolerance

A piece of cork cut into the shape of the body of a spider, and a bit of thin wire for legs, will represent with tolerable exactness this insect. Put a small quantity of the silver underneath it and on any female espying it, she will naturally tread on it, to crush it, when it will make a loud report. 

Potatoes with hard, dark, corky spots in the center of flesh. Cause Internal cork. This condition develops if storage conditions are too warm and may be caused by a viral disease. Store potatoes between 55° and 60°F to reduce problems. Prevent problems by planting tolerant cultivars such as Allgold , Centennial , and Nemagold . 

It is not long since the stoppered or corked bottles were the basic containers for both the pharmaceutical and the toiletry trade. Although these still exist, their use rapidly declined with the advent of the screw-necked container. In more recent years glass has used wadless closures which started as screw versions but can now be applied and removed by other means plug, twist-off, lever-off, etc. In these forms the flexibility of certain plastics have been utilised to provide both the resistance and the resilience required of a closure. Although press in/over closures can be applied at a higher speed than screw caps, tolerances for bottle neck and closure have to be tighter.
