Is it best to add powder to water, or water to powder? I had a disaster with my last batch (3.5ltrs for a hand cast), where it turned instantly crumbly instead of the pourable syrup I was expecting, then stayed as a mess of wet crumbs that wouldn't dry/set properly.

Please find below instructions as requested:
Instructions:
1. Measure 1 part alginate to 3 parts water (eg 20g alginate / 60mls water)
2. Mix vigorously for 30-40 seconds
3. Pour over object to be moulded and leave to set for approx 4 minutes
Always do a small test before using the whole bag
Warm water will reduce setting time
Mixed alginate should be cast immediately
If using on your skin, test on a small area first to check for irritation or allergy.
Hope this helps.

A high quality, dust free alginate. Simply mix with water and cast. Perfect for taking quick and highly detailed impressions from almost any material. It is ideal for taking moulds directly from the skin.
