Take the materials we use every day to make our customers’ lovely casts. Just dental alginate powder to create the moulds, and good old plaster of Paris to make the casts. It turns out our craft has an unbelievable heritage!
Would you believe, for example, that making moulds began with a bottom print in the sand, 5000 years ago? A sharp-eyed craftsman realised that shapes could be reproduced from impressions, and we’ve been doing essentially the same thing ever since (and yes, we’re still making cute little bottom casts!).
But it wasn’t until the 1920’s that dental alginate first appeared. An Austrian inventor experimented with common brown seaweed, and discovered that when dried, processed and added to water, it produces a gooey substance which makes our perfectly detailed moulds.
That’s only half the process, though. The rubbery alginate mould must be filled with liquid plaster to make the cast, which is the basis for every single one of our products.
The first use of plaster was discovered recently to be in the Egyptian pyramids! Again, that’s about 5000 years ago, just like the origin of moulding – quite a coincidence! But it was plaster of Paris that made the name for plaster, and did actually come from Montmartre, just outside Paris.
So, what a history our little plaster casts really have, and what a wonderful addition to the story of every set we make for our customers!
