These are usually straightforward,always obtain a roungh melting point before attempting to make accurate measurements and it is often useful to 'calibrate' the apparatus by measuring a known(pure!)compound with a similar m.p. to the product If there is a significant discrepancy then a more reliable apparatus must be used.Do not forget to get the inacurate apparatus repaired,and discard it if necessary.The compound needs to be pure and free from dust and the temperature must be raised very slowly as you near the melting point.If there is a range over which the compound melts(there usually is)then record it;do not estimate an'average'reading.If a capillary tube is used,it is sometimes useful to examine the upper part of the tube for sublimate or distilld decomposition products.
If you have distilled your product to isolate and purify it then you should already have the information required for reporting the boiling point.It is important to quote the range of temp
