My colleague and me are visiting every week a famous glassmaker in Sydney, Australia to get us up to speed with boro glass making. In our 2nd session I came up with the idea to make a boro glass octopus. I have seen this beautiful boro glass creature quite often on Etsy and this time I decided to DIY instead of buying it!

After talking to our teacher how to do it she demonstrated it to us - see video and after that we made our own octopus. I summarized below 15 Simple Steps on how to make a boro glass octopus.

Materials needed to make a boro glass octopus:

  • 15cm of clear glass
  • We used Boro Trautman Art Glass 33
  • Long rod of neutral colour (Opaque WYSIWYG) for body (500mm)
  • Long rod of boro colour glass for body and tentacles (600mm)
  • Rod of other colour to make the eyes (10mm)
  • Any other colour you want to add to make it look more spectacular

Tools needed to make a boro glass octopus:

  • Torch & Kiln
  • Tweezers
  • Shears
  • Peters Tweezers for the eyes
  • Eye Protection
  • Graphite Paddle
  • Graphite Reamer

We used for our octopus boro Trautman Art Glass 33 colours. As a glass supplier in Australia and lots of sample colours we were able to use as many colours as possible. For the octopus you can use clear glass or colours.

Step 1: Melt a Big Mass in the Flame for the Body

Put your eye protection on and start your torch. Take the rod and melt a big mass in the flame, around 20mm. When melting the glass, always make sure to keep the glass 70mm away from the burner. Glass should not get onto the burner head. We used for the body aWYSIWYG colour and melted it with a colour changing colour – Double Mai Tai. Colours look much more intense and exciting if they are over a neutral base rather than over clear glass. You can use a Graphite Paddle to form the hot mass on a heat resistant piece of material.

Step 2: Cover Mass With Colour

When you melted a 20mm round ball cover it with a spectacular colour. Heat the colour rod and the mass until they glow in the same red/yellow colour and melt the rod from the top to the bottom downwards. Heat the mass with the attached colours until no more black shades are visible. Make sure the two colours are well melted together.

Step 3: Attach a Handle

Attach a rod of clear glass on the head of the octopus. The longer the clear rod the less heat your hands will be exposed. I suggest a long clear rod (30mm). With two handles now attached it is much easier to rotate the mass and heat it up.

Step 4: Put Handles Slowly Apart and Form a Peanut

Heat the mass until you can form a long peanut shape. This works best when you pull the two handles in the flame slowly apart.

Step 5: Remove the Colour Rod on Top

When you are satisfied with the peanut shape remove the colour rod from the bottom and keep the clear handle on the top.

Step 6: Flatten the Bottom for the Tentacles

Heat up the bottom of the peanut shape until it glows and press it on a heat resistant material so that the bottom is flat. Use the graphite paddle to flatten the bottom. Heat up the bottom until it glows and keep flattening it. In the next steps we will cut the glass and attach the tentacles to the bottom.

Step 7: Cut the Flat Bottom Into 8 Pieces

Heat up the bottom until it glows, take your pair of shears and cut the glowing flat bottom in 8 pieces. Don’t put the shears into the fire. After every cut the bottom of the mass has to be heated and glowing.

Step 8: Attach to the 8 Pieces the Tentacles

After cutting the flat bottom in 8 pieces choose either the same colour rod that you have used before to attach the tentacles or choose another colour. For my second octopus I used for every single tentacle another colour, mainly to see the variations of colours that we have.

Step 9: Attach to the 8 Pieces the Tentacles

Heat up the cut piece and the road you want to attach until it glows and attach it to the body. Pull the rod straight and make a twiddle at the end to form a tentacle. Repeat this 8 times until you have beautiful tentacles attached to the body.

Step 10: Attach Eyes to the Body

Heat the part of the body where you want to have the eyes of the glass octopus, use your tweezers to make two holes. Take a rod in another colour, heat it up and melt it into the two holes.

Step 11: Test the Balance of the Octopus

Now it is time to make the balance test for your octopus. Make sure it stands straight; otherwise you can just heat the tentacles up again and put them in the right position.

Step 12: Remove the Handle

To remove the handle on the head of the octopus, heat up the top until it glows.

Step 13: Check the Balance Again

Form the tentacles with your graphite reamer in the flame in the right shape that the octopus balances on his tentacles.

Step 14: Remove the Other Handle

Hold the glass octopus with tweeters and heat up the spot where the clear glass handle is attached and melt it off.

Step 15: Put Octopus Into the Kiln

Quickly into the kiln. Our teacher recommended for 3 hours but it depends on the size of the octopus.Check out the whole video how our teacher made the boro glass octopus.

<p>Nice! :)</p>
Because I did not know the word &quot;boro&quot; I looked it up and will put the definition here for all to see. <br>As per Wikipedia.en:<br>Borosilicate glass&nbsp;is a type of&nbsp;glass with silica and boron trioxide as the main&nbsp;glass-forming constituents.Borosilicate&nbsp;glasses are known for having very low coefficients of thermal expansion (~3 &times; 10&minus;6&nbsp;K&minus;1&nbsp;at 20 &deg;C), making them resistant to thermal shock, more so than any other common&nbsp;glass.
Wow! I've always been a bit afraid of working with glass, but this looks fun!
<p>It is! I just started 2 weeks ago and it is heaps fun!</p>
<p>So cool!</p>
<p>The octopus is so cute with its rainbow body!</p>
<p>Colour is Trautman 033 Double Mai Tai on Trautmna 033 Opaque White</p>
Great work. can I ask who the glass blower in Sydney is. I've been trying to find a glass Working teach in the area for ages. very keen to get some pointers rather than YouTube videos and trial and error on my garage.<br>thanks<br>Andrew
<p>Sure Andrew it is Penel Biggs from Fire Bird Beads. Great teacher!</p>
<p>Octopus after the kiln. It is pretty obvious which one's are from the teacher :-P</p>
<p>Wow! This is great! I wish I had the materials to make something like this!!! </p>
<p>If you are a beginner start with some clear or odd glass- cheaper than the premium colours.</p>
<p>Cool! Thanks so much! :)</p>
beatiful
