Custard powder is not dried, powdered custard. It is actually a powdered mix used to make custard, and it is very similar to the type of mix used to make instant pudding in the US. Just combine it with milk, cook to thicken, and you have custard (or pudding)! Custard powder is primarily made up of thickeners that give the pudding its texture. Cornstarch is usally the biggest component, since it is great for thickening liquids, disolves easily and is almost foolproof.
Pumice powder is an abrasive material used in the application of varnish, shellac or lacquer to produce a fine hand-rubbed finish. It is obtained by grinding volcanic ash into powders of different degrees of coarseness. Pumice powder should be sifted through cheesecloth before using to make sure particle size is uniform. Large particles or specks of dirt can cause scratching. Pumice is used for the coarse rubbing of a hand-rubbed finish. In other words, it is the abrasive used when you are building up the body of the finish. The fine polishing, or final work on your finish, uses rottenstone as the abrasive.
