Product description ------------------- Fast setting Alginate 3 - 3.5 Min (Approx) Add 100g of powder to 250ml - 300ml of water, for a full 450g bag of alginate you would add 1350ml of water. You can add more water than this ratio which will thin the mix which will slow the setting times of the above chart, a thinner mix helps to reduce air being trapped in the mould. If spreading the alginate onto a model it is not recommended to add more water than the standard mix ratio as it becomes too difficult to spread when thin. Polycraft Chromatic Alginate is a non-toxic non-enic moulding material which is safe to use on all areas of the body. Its chromatic feature ensures ease of use as it changes colour during the mixing and setting process giving you a visual indication at each stage of the process. As with all fast setting moulding materials preparation is crucial, have all quantities and materials measured and ready for use. Ensure that the model is aware before starting of how they should pose, perform a dry run to avoid material wastage, if casting hands ensure model is aware not to curl fingers as air may get trapped underneath the fingers. If moulding hands or feet you can use polythene bags or drink bottles or a plastic containers. The advantage of using plastic containers is that the container will in turn become a support jacket for the mould however you do use more material with a container than plastic bags. If casting onto any area with long hair use a petroleum jelly such as Vaseline to act as a barrier, do not use the petroleum jelly on non hairy areas such as s as the alginate will slide off. It is recommended to try a small sample first to get used to how quickly you must work with the product as you only get one chance of use. Best to use cold / look warm water as hot water will cause the alginate to set almost instantly.
