3:1:1:1
sand : fireclay : portland cement : hydrated lime

Mix first then add water as required - and mix to a workable consistency. This bit is not so exact. You don't have to adhere (sorry) exactly to the recipe. More fireclay is said to add to stickiness,

That is a good article, but it really has no relevance to refractory mortars. Here in the states, in recognition of exactly what the article discusses, the specification is "from 2-1/4 to 3 parts sand by volume of the cementious materials".

Do yourself a favor and try it at 6:1:1:1. It is more workable and less prone to cracking as well as heat decomposition. The 3:1:1:1 is based on a misinterpretation of the specification.
