More About ‘Lost Wax’ Method In Crafting Bronze Statues

The traditional process used to cast bronze, developed and used 4,000 years ago, is called lost wax casting. This method results in highly detailed, quality castings and has changed very little over the centuries. The method was used by craftsmen and artists from every culture from ancient Mesopotamia and Egypt up to today.

As for Thankgkas (religion based paintings), according to K.B. Lama of Dharmapala Thangka Centre in Durbar Marg, one will be lucky to find genuinely antique Thangkas. ‘Nowadays very few old Thangkas come from Tibet,’ says Lama. He exports Thangkas to Europe and has held a lot of exhibitions abroad. A 6x4ft. Thangka depicting the Gelungpa Sect Lineage is priced at Rs. 4,00,000.00. A twin set of Thangkas depicting Dharmapala Manadala and Amituyus Buddha based on Japanese style costs Rs. 4,00,000.00.

But here’s the thing. Observing David only from the rear casts aside an important part of the story. You can’t tell from the back that the boy-warrior is readying to do battle. You see only an uncertain gesture, perhaps even slightly cowering, which makes his effort – made apparent solely in the front – all the more valiant. Bypassing the front, you miss the easy stance, as if David were waiting for a bus, which belies his qualms about battling Goliath. You miss the seeming calm as he faced Goliath, furtively palming a stone in one hand and the sling for it flung ever so casually over his shoulder.

The foam original will be replaced by the molten metal unlike the Lost fusione a cera persa where a wax mold is made of the original and then coated with a ceramic shell in preparation for the molten metal. Luckily, most foam is pretty inexpensive so the loss of the original shouldn’t pose a significant financial loss, just an annoying creative loss.

Even metal fresh from a jewelry supply house package has residue, oil from machinery or from manual handling or dirt from sitting around. Metal can have rust or pitting. It can be tarnished. Whatever way you choose to transfer a design, clean metal can receive it better.

‘Bhote talchas’ (locks) with single lever costs about Rs.2000.00 while double locks cost Rs.3500.00. A ‘kafi techya’ (Newari tobacco box) costs Rs. 6000.00 and ‘thekis’ (old vessels used in making curd) costs from Rs. 400 to Rs.5000.00 depending upon size. Tibetan chests and boxes are comparatively more expensive and can cost from Rs.10000 to Rs. 1,25,000.00, again depending upon size. Of course, there is no fixed price on curios.

The burnout step is removing the wax from the mold. Since you want the mold to have a bottom, you leave the bottom of the mold in tact and just expose the ends of the gate channels. When the ceramic mold is placed into a kiln to cure, the wax melts and runs out of the channels, this leaves the inside hollow, ready for the bronze.
