Hello. I want to start publishing my new project - the process of making a large glass sculpture - a glass statue of a girl of 180 cm high (70.87 inches).
First, I will explain some technical solutions. For stability during transportation and overall reliability of the structure, I decided to mount all parts of the statue with each other and even more with the main load bearing mounting plate. It will be a sheet of black glass 2 cm thick. Of course, for a delicate translucent glass, the statue has a good contrast with rough dark granite, but for me it's expensive now. To connect all the parts of the statue with each other, I use UV glue, and for the mounting to the plate I use silicone sealant - this will give some flexibility to the whole structure. If necessary, the sealant can be cut with a thin knife and detach the statue from the plate. Inside the statue, I want to place a light source and thus it will be a large sculptural lamp on the wall for example in the interior of a hotel, restaurant or home. If the owner wants to cover up the nakedness of this statue (for example, in Asian countries), this can be done using a organza tunic, it will be like a lamp shade, and also beautiful.
The most difficult parts of this statue are the head and feet. For these parts I will make ceramic graphite molds. For all other parts of the statue - legs, arms and body I will make simple ceramic molds - this is another technology. This allows you to get 50 - 70 glass items of sufficient quality. But a simple ceramic mold is made very quickly 1 - 2 days. Therefore, I myself wonder how much time I need to do this glass statue. I made a gypsum model for about three weeks, but after separating the parts, I can change something else. During the process, I will add a photo and description.
The photo shows where the borders of the statue's parts will be. In total there will be 12 parts.
The statue is sawn in 12 pieces. Now the parts must be very accurately prepared for connection with each other and make an additional fixation with the lodgment for all parts relative to the mounting plate.
Over the past two weeks (10 working days 5-7 hours each) I have made an accurate connection of all parts of this gypsum model.
Each part loosely lies on the lodgment and moves along it horizontally (a glass slab).
These lodges will be used to join the glass parts using UV glue. Now every part of the plaster model needs to be prepared to make mold. To do this, you need to make excess volume on top and bottom, designate a line to cut off excess and mark 4 points of the exact line of joining each part. I'm not sure about the accuracy of the translation, but the picture will be clear.
On this photo part of the statue is below the chest, as it should be made of glass.
To accurately indicate the connection line of this part with other parts, I painted it in red. Then I made an excessive volume at the bottom and at the top of this part (it is clearly visible, because it is white).
A glass ball of this form I should have using this mold. When the glass cools, I need to cut the excess from below and from above. The photo shows a relief line of an approximate cut. Then I need to have an exact line of the boundary of this part on the horizontal plane. For this, I made four protrusions along the perimeter of each border. After an approximate cut, these protrusions will be a good reference point for the necessary grinding. On the plane of the grinding wheel, I must remove the excess around the perimeter, until all the protrusions disappear at the same time. For this, I need to determine the desired angle of grinding, so that all the lugs are sewn the same way. Having done such operations with another part of the statue, I have almost complete coincidence around the perimeter of these parts. Mismatch may be a maximum of 0.2-0.3 mm. For 3-5 cm of the perimeter length. This can be seen in the photo of this statue of 3 parts.
The line connecting two parts (bust and torso) is under the chest of the statue. After gluing these parts, the mismatch simply aligned with polishing, but I did not have the necessary tools and time, and the customer was in a hurry and satisfied with this quality. If glass matting is not used by sandblasting, the mismatch of the parts inside from different wall thicknesses is clearly visible. I plan to even this discrepancy (after gluing) using (pouring) a viscous consistency polyvinyl acetate colorless plastic. This gives a very good alignment of the unwanted terrain inside.
For a long time I could not return to work on this project. It is a pity, but the general economic situation forces me to postpone this for an indefinite time - not everything depends on me.
For more than 2 months, we stopped the fire in glass ovens, because people in country are now saving their money for possible future "bad times" and are afraid to spend it on our "unnecessary glass". Here is a photo of my project for today, I did it for a long time.
You see all parts of the statue ready for making molds for them. But for this I need money that I do not have. I have never been so close to completing such an impressive project. But my income of $ 350 per month is too small to continue this work. I think that there is only one way to continue this project - crowdsourcing. I want to offer all workers of fusing, bending and cast glass a new technology as possible to make strong metal molds for molten glass. This very simple process makes it possible in a garage, on a table or even on the floor, with the hands of one person to make an enormous, accurate, metal mold for a hot glass in an acceptable short time. It can be a large glass bas-relief, a large glass sculptural washstand like a rose or starfish or your any other desire. Your artistic fantasy should not be limited to the size (only as the size of your bending oven) or the complexity of the sculptural relief. The cost of this metal mold is exactly equal to the cost of the weight of cold metal in the store, plus $ 10-15. I think there is no difference in selling an art object or selling technology for glass artists. Otherwise, I have to completely stop my work. I want to offer for everyone interested in this technology my e-mail with a detailed description of the process in exchange for a small amount of money - for example, $ 200. I hope that this will provide an opportunity to continue my work for a large glass statue. Unfortunately, in my country the Pay Pal system operates with great restrictions, but I have a very good friend in Melbourne, Australia. I would like to know your opinion. Thanks.
