In our 3D lessons recently we have been working with pewter. For our first attempt at this process we chose our favourite animal and drew the outline onto a very small section of MDF wood. On the band saw be cut around it and was left with our small version of that particular animal. I chose to make a lion!
I then grabbed a pre-made wooden box to place our MDF animals in. Then using a hand saw we made a funnel so the pewter could be poured in through.
Once we were ready we mixed up rubber with a hardener so the latex would set to form our mould.
Once we had poured enough we left it to harden for a week or so.
We were ready to pour our pewter moulds in. We pealed our plastic mould away from our MDF template and box. We also started heating up the pewter on a portable hob. The pewter was extremely hot so we made sure to wear protection like gloves and glasses. we carefully removed the unwanted layer of purities in the pewter and poured into our mould pressed against wood.
We left the pewter to cool for a few minutes and pealed it away from the mould and after we removed the unwanted edges with a saw we was left with a final piece.
The only thing left to do was to sand wet and dry and polish to get the pewter looking its best. I really like this process. The outcomes look very high spec. We will be creating a letter for our homage to books project! So keep your eyes pealed!
