The bulk of Pat's time is taken over with the Hypertufa production. Hypertufa is a mixture of cement, vermiculite, peat moss and a small amount of fibre mesh. The fibre mesh acts as a bonding agent. The proportions are measured into a large tub and then mixed all together in their dry state. Once they are blended water is added. At his stage it is crucial that you do not add excessive water, as your batch will be runny and you will be throwing it out. You must add your water in smaller portions and mix it with each addition. The consistency you want to achieve is that of cottage cheese. Once the consistency is satisfactory you can start molding your containers.
Check back next week for instructions on Part II of Hypertufa Production.
