Technology Hard Materials

 Today at technology my class and I went to tamaki college to do the rest of our pewter casting work on how to build a necklace by melting the metal and pouring it into a mold that we made with a small wooden platform that's called MDF. After pouring the melted metal into the mold and letting it cool down we would start to try and finish of our work on a doc that Mr grundy our teacher sent to us to do. I already done all of it so I am on the part were I have to use a certain sandpaper to help smooth and soften the sides and the edges of the pewter necklace. On each sandpaper there's a number that helps to identify which sandpaper it is because every sandpaper is different. So the first sandpaper I had to use was the number 180, I started using it to scrub the bits that were not as smooth and not as soft as the other. After done I started to use 400 and 1200 and started to scrub the edges and sides, I then repeatedly did it over and over again.

At technology my group and I got the chance to make a necklace for our loved ones. First our teacher explained that we should start of by making a wooden mold for the melted metal so that it can form the shape and size that I want it to be.  When I was done making the wooden mold for the metal, Mr Grundy informed that I should wait for the metal to melt so when it's ready he will call me. In my opinion the metal didn't take that long to melt because it was a small necklace, the metal used to look like a block until it fell into the hot and steamy platform, turning itself into a small, grey,liquidy pool. Once the metal was ready Mr Grundy poured the liquid into the wooden mold. After the metal was dried up in the mold my teacher Mr Grundy took it out and explained that I had to use a sand paper and tools to make my project more smooth and ready to be worn, soon after the bell rang and my group and I had to leave. I almost finished the project and hopefully I will be done next week tuesday.

  In technology my group and I went to our class which is called hard materials (Pewter). The class was really fun and the teacher is also nice his name is Mr Grundy and he's very busy because he has to work on helping the students and help melt the iron because students can't do it. Mr Grundy is a wonderful teacher and I hope to see him everyday next year. Mr Grundy teaches us how to make necklaces and i was very lucky because i finished of half of the worksheet that we were supposed to do. I had to shade the shape and outline the shape after that I ended up cutting out the line to make a mold for the melted metal after that the bell rang and we had to go back to school.
