Inscription.
Sewah Studios was founded in 1927 by Mr. E. M. Hawes and began operations on Marietta's west side at the site of the former Stevens Organ Factory. That facility was destroyed by fire in 1932 and a new factory was built on the Millgate property on Muskingum Drive. In 1954, the company was purchased by Mr. Gerald E. Smith and Mr. Lloyd M. Thomas who continued to operate and expand the company at the Millgate facility. In 1959, land for the current site was purchased and a new building was erected. The company has operated continuously at this location since that time.
– – Sewah is Hawes spelled backwards – –

4. Making the Pattern
Once the layout of the marker is finalized, letters are individually glued in position on the textured backing board. The glue allows the letters to be removed and reused. After proof-reading and inspection it moves to the foundry area. When ready for casting, it is called a “pattern”.

Fine sand is sifted onto the pattern. Fine sand preserves the details of the textured background, letters and decorative elements.

6. Foundry
A frame called a “flask” is placed over the pattern and filled with coarse “green sand”. The green sand is compacted to retain the shape of the pattern. After compacting, the flask is flipped over and the pattern removed. The process is repeated with another flask for the reverse side.

7. Ready for the Other Side
Here is one face of a marker after the pattern has been carefully lifted out. All letters and decorative elements of the pattern will be reused. The flask for the reverse side will be mated to this. Molten aluminum is poured into the mold to fill the cavity left by the patterns.
