MR. BIXBY: There is a series of paraffines pure paraffines which are known only in chemical laboratories and also a number which can be obtained without much difficulty.

We may then settle the question of obtaining paraffines which have a high melting point, by knowing that they may be obtained from any of the Standard Oil people.

Hickory buds will burst their way through almost any thickness of grafting wax, but when the paraffines are used without pine gum admixture the paraffine over the buds is particularly apt to crack and to allow the graft to dry out.

Slide 16: Organic PCMs • for instance paraffines or polymers • heat conduction of material determines charging power, length of polymer chains determines melting temperature • relative to anorganic PCMs: larger melting heat and higher heat capacity • uniform melting behaviour, stable, non toxic, non corrosive • suited for impregnation of building materials • prevention of evaporation, odours and volume changes by encapsulation • available in different forms
